- Product Description
Premium Sodium Acetate Trihydrate for Chemical Analysis – Laboratory Grade Reagent with 99.5%+ Purity
SHANXI ZHAOYI CHEMICAL CO., LTD supplies lab chemical reagents that meet tough standards. High-purity Sodium Acetate Trihydrate for Chemical Analysis is one of our main products. Purity sits at 99.5%, and trace impurities stay under tight control. Our work with acetate products began in 1988. That gives us over 35 years of hands-on experience. The production plant is modern and covers 27,000 ㎡. It runs at a steady 150,000 tons a year. Lab analysis work has strict quality demands, and this output meets them.
You get analytical grade with this reagent. Its molecular weight is 136.08 g/mol (CAS 6131-90-4). Iron levels stay very low, under 5 ppm. Crystals hold a stable, uniform structure. Results stay accurate and repeatable because of it. Titration testing is one job it handles. Mixing buffer solutions is another use. Chromatographic analysis and other lab work also fit.
Key Features & Benefits
Laboratory analytical experiments require extreme precision and stability, and our this product is professionally optimized for various analytical scenarios, bringing core advantages for laboratory use:
High-purity residue-free dissolution: Colorless crystals are the form you get. They dissolve easily in water. Breakdown happens fast, and nothing insoluble is left behind. So the solution stays pure, and that counts for accurate analytical testing.
Very low interference from impurities: Traces of impurity are capped at tight limits. Your readings will not drift because of stray contaminants. Sensitive work suits this product well. So do high-precision analytical procedures.
Stable storage performance: This product has a fixed, stable makeup. Under normal storage, nothing breaks down and it does not lose strength. Reagent quality holds steady from one batch to the next, so it lasts through years of lab use.
Accurate formulation support: The crystalline powder is uniform, so each particle can be weighed out exactly, by hand or by machine. Standardized reagent prep then becomes possible. Data from experiments can also be reproduced.

How It Works
This reagent is for lab analysis work. The chemical properties it has give steady, accurate results. Following how it works is easy. It fits many different uses too:
Buffer pH stabilization: This compound serves as the conjugate base in acetate buffer systems. Drop it in water. Acetate ions come out. Those ions settle into a steady balance with acetic acid. The solution pH stays between 3.6 and 5.6 because of that balance. Analytical tests need tight pH control. They get what they need.
Standard titration calibration: A molecular weight that stays fixed and a makeup that does not change make it a reliable primary standard reagent. Titration experiments are a good fit for it. The water content stays the same from batch to batch, because the trihydrate structure holds steady. Calibration errors are avoided that way.
Fast pH control: Acid left over in test samples is neutralized right away. It dissolves in water without any trouble. So a standard solution can be mixed on the spot. Stirring for a long time is not needed. Heating is not needed either. That makes lab work move much faster.
Applications
With ultra-high purity, low impurity and stable performance, our Sodium Acetate Trihydrate for Chemical Analysis is widely applicable in various high-precision laboratory scenarios:
Analytical Chemistry Laboratories: The main use is to prepare standard acetate buffer solutions. Titration work depends on it. Reagent calibration does too. Other routine analysis uses it as well. Results stay stable and can be repeated.
Biochemical Testing: Enzyme activity detection runs well with it. Protein purification does too. Other biochemical experiments fit as well. With few impurities, biological reactions face less interference. Results come out accurate.
Chromatography Methods: Metal levels are ultra low. Columns stay clean, and the baseline holds steady. For mobile phase preparation in HPLC and ion chromatography, it is a good fit.
Laboratory pH Adjustment: It serves both sample pre-treatment and pH adjustment in experimental systems. Leftover acids are neutralized fast. The test environment stays neutral and stable.
Academic & Industrial R&D: University labs count on it, and so do R&D groups at companies. Organic synthesis is one job it covers. So are product quality checks, research work, and other tests.

Manufacturing Process
We adopt a refined full-process production system to ensure the high purity and stable quality of analytical-grade reagents such as Sodium Acetate Trihydrate for Chemical Analysis, with standardized production steps as follows:
Using Very Pure Raw Materials: Pharmaceutical-grade acetic acid and sodium hydroxide are what we start with. So impurities in the raw materials never interfere at the source.
Synthesis with Tight Control: The neutralization reaction runs at a constant temperature. Stirring stays steady throughout. Raw materials then react fully and evenly.
Purification & Crystallization: We do secondary recrystallization. Then we filter in several stages. This takes out trace impurities. What is left is trihydrate crystal particles that are all the same size.
Constant Temperature Drying: Drying takes place at one steady temperature. Equipment with a controlled atmosphere holds moisture content at the exact level needed. The trihydrate structure stays stable because of that. Batch to batch, product indicators do not change.
Batch Testing & Packaging: Every batch gets full-index testing before it leaves the factory. Sealed packaging, done by machine, keeps secondary contamination out.
