- Product Description
99.5% Pure Sodium Acetate Trihydrate | Industrial & Laboratory Grade | High-Purity Chemical Solution
Acetate is the product Shanxi Zhaoyi Chemical Co., Ltd. turns out. Our plant has run since 1988. That works out to more than 35 years in the business. The workshop covers 27,000 ㎡ under a standard layout plan. Each year we hold output at 150,000 tons. ISO quality management systems are followed to the letter, which keeps our chemical materials inside spec. Precision crystallization technology goes into the 99.5% Pure Sodium Acetate Trihydrate (CAS: 6131-90-4). Purity stays above 99.5%. Total impurity content sits under 0.05%. Crystals come out colorless and transparent. Water solubility reaches 123g/100ml at 20°C. Pharmaceutical synthesis is one place it gets used. Precision laboratory analysis is another. Industrial buffer preparation also fits. Anywhere strict component accuracy and stable performance matter, it does the job.
Key Features & Benefits
Steady buffering for precision experiments comes from the trihydrate chemical structure (CH₃COONa·3H₂O). That is what makes it work. With this product, buffer capacity holds up right across the pH range of 4.5–5.5. Reagent quality that drifts around ruins experiments, and the data comes out skewed. Here that problem does not come up. Enzymatic reaction work asks a lot of a reagent. So does precision analytical testing. This product delivers on both counts.
It dissolves fast, and that saves time on the job. Next to anhydrous sodium acetate, this trihydrate product drops into solution quicker. Mixing and preparing buffer solution then takes almost 40% less time. Almost no organic contaminants sit inside the ultra-transparent crystal structure. So pharmaceutical intermediate products stay free of contamination. Spectral analysis is left undisturbed.
This product keeps heavy metals at very low levels. Every rule in the international pharmacopeia is followed to the letter. Lead sits under 2 parts per million. So do arsenic and mercury. Other heavy metals come in under that same number. That makes the manufacturing and testing compliant for markets in Europe, America and Asia. Delicate experimental setups stay protected too. The same goes for high-precision formulas.

How It Works
99.5% Pure Sodium Acetate Trihydrate dissolves fast in water-based solutions. It breaks apart completely, into sodium cations and acetate anions. Acetate ions work as efficient conjugate bases. Their job is building an acetic acid-acetate buffer system. That system holds firm when the pH of the solution jumps around, and it keeps the reaction environment stable.
Dose this reagent with care and chromatographic testing conditions get better. Standard acetate buffer solutions become easier to prepare. Enzyme activity holds steady too. Dissolution brings balanced hydration, and the three crystal water molecules stay fixed. Experiments turn out more accurate and faster because of that. No more working out water ratios over and over while you prepare a formula.
This material is used as an acetylation raw material in industrial synthesis. It also acts as a moderate alkaline regulator. Chemical synthesis stays under control with it. Reaction activity remains steady and predictable. That is why it shows up in pharmaceutical intermediates and textiles.
Applications
Pharmaceutical Manufacturing: When this material serves as a key raw material for API synthesis, adverse reactions stay away. High purity and low impurity levels are the reason. Tight toxicological compliance rules are satisfied. It can help make injectable buffers as well. Dialysis solutions can be made with it too.
Laboratory Analysis: Standard buffer solutions for biochemical tests, electrophoresis work, and HPLC detection are something it makes well. Quality holds steady from batch to batch. Accurate, repeatable experimental results come from that.
Textile Industry: Dye soaks in faster and more fully with its help. Color lasts longer too. During processing, delicate fibers are shielded from chemical harm. Dye bath pH shifts because of this product, and it keeps that value steady.
Electroplating Operations: It works as a pH stabilizer inside nickel and chromium plating baths. A complexing agent as well. Metal coatings hold on tighter and cover more evenly thanks to it.
Chemical Synthesis: Provides a source of acetate for chemical synthesis substitution and esterification operations. It complies with green and ecologically friendly production standards by substituting harsh chemical reagents.

Certifications & Compliance
Authoritative Quality Certification: ISO 9001:2015 quality management system certification is held by our factory. Standard controls run through every stage of production. Batch quality stays steady that way.
Compliance for Global Markets: Valid KOSHER and HALAL certificates come with this product. Market access rules in many regions of the world are covered by them.
Pharmacopoeia Standard Compliance: Specs from USP and EP are followed exactly. A full test is run on every batch. Nothing ships until that test is done. COA quality documents come with the goods in full.
Packaging Options
Standard Packaging: 25kg multi-layer paper bags, with a PE lining inside. The PE lining keeps moisture out. Without it, the product would spoil. It works well for normal lab work and small industrial runs.
Bulk Industrial Packaging: Fiber drums and woven bags cover orders from 50–500kg. You pick the size you need. Every unit has an inner lining. Automated feeding equipment takes them as they are, which works well for continuous, large-volume output.
Complete Batch Documentation: Every package carries a clear batch number. The production date sits on the label too, together with the operation instructions. Bulk goods get shrink-wrapped and palletized. That keeps the product intact through long-distance transport.
Manufacturing Process
Our production technology is mature and precise. We have built it up over 35 years. Every step of production is tightly controlled, so the purity indicators of the product are guaranteed:
Precision Neutralization Reaction: High-purity acetic acid and sodium act as the raw materials. Through neutralization, the temperature has to hold steady. pH control must be tight. The reaction then runs far enough, so no extra alkali is left behind.
Constant-Crystallization Process: Stainless steel evaporation crystallization equipment handles this step. Keep the cooling rate steady. That way you get even crystal particles, and the trihydrate structure stays intact.
Multi-Round Purification & Screening: Leftover mother liquor gets pulled out by multi-stage centrifugation. After that, drying runs at a set temperature and a set amount. That keeps the standard crystal water in place. Automatic screening equipment takes the last step, sorting particles by size.
Full-Batch Quality Inspection: Every finished product goes through metal detection. We also pull random samples and check those. Before anything is packed or shipped, all indicators get tested against the standards.
