- Product Description
Sodium Acetate Trihydrate CP Grade – Premium Laboratory Chemical for Reliable Analysis & Research
Sodium Acetate Trihydrate CP Grade (CAS: 6131-90-4) comes from SHANXI ZHAOYI CHEMICAL CO., LTD. This reagent is chemically pure. Labs use it for analysis. Scientific research relies on it too. Acetate has been our line of work for over 35 years. We began back in 1988. The production base covers 27,000 ㎡. Every year we turn out 150,000 tons. That number holds steady. Effective content in the CP grade runs 99-100%. Impurities stay at very low levels: chloride ≤0.005%, iron ≤0.0003% and heavy metals ≤0.0005%. Everyday lab tests depend on it. So do research projects. Accurate results come out. They repeat as well.
Key Features & Benefits
Our this product has high purity and few impurities. Lab test results stay accurate because of that. Repeat runs work too. The crystals are colorless. They pull in moisture as well. Water dissolves them fast. Buffer solutions and pH adjusting liquids are ready in minutes. That cuts your lab hours. Daily lab work and teaching suit this standard chemically pure reagent. It costs less than high-end AR grade reagents. In water it turns mildly alkaline. Buffering and pH control hold steady. Teaching experiments are one use. Industrial research is another. Routine chemical synthesis fits as well.

How It Works
Buffering from this product works through a weak acid and conjugate base balance. Once it dissolves in water, acetate ions take in extra acid and base found in the solution. pH values hold steady. One common job for it is plain pH adjustment. Alkaline conditions get created, and you can control them. Chemical reactions get help from that. Sensitive experiments stay calm too. As a dependable acetate source and a mild alkaline catalyst, organic synthesis leans on it. Hydration comes from the trihydrate structure. That hydration stays even. Crystallization and precipitation reactions turn more precise. Results are spared from sharp pH swings that would spoil them.
Applications
Lots of lab teams work with this reagent, and industrial researchers do too. Teachers bring it into classrooms for lessons and for student practice. Organic synthesis is another place you will find it, where it acts as a mild catalyst. Analytical labs stir it into their standard acetate buffer solutions before testing. Industrial labs come back to it for pilot work and formula development. Solution treatment is a further job it handles, covering pH neutralization and adjustment. Many industries also count on it for routine quality checks and calibration.

Certifications & Compliance
Our factory is certified with ISO quality management system, implementing strict full-process quality control. All CP grade products meet standard chemically pure specifications for laboratory use. SGS and Intertek third-party testing verify stable product quality. Supported by KOSHER and HALAL certifications, our products adapt to diverse global market demands. Each batch is attached with complete compliance documents and COA reports to achieve full quality traceability.
Packaging Options
We provide diversified packaging solutions for Sodium Acetate Trihydrate CP Grade in different usage scenarios: 500g bottles and 1kg containers for small laboratories and teaching institutions; 5kg drums for daily research use; 25kg bags for industrial research and high-volume procurement. Custom packaging is available on request. All packages adopt moisture-proof sealing, with complete product specification, safety data and batch coding labels.
Manufacturing Process
Certified raw materials come in at high purity, and we keep a close watch on the ratios. Reactions take place in reactors held at a constant temperature. This lets them run to completion and reach the standard hydration degree. Crystallization stays under control, so the trihydrate crystal products come out qualified. While a batch is being made, impurity detection and performance testing get run several times. Drying, screening, and packing come last, done in an area free of dust and moisture. That keeps contamination out and quality steady.

FAQ
Q: What sets CP grade sodium acetate trihydrate apart from AR grade?
A: A1: Purity of CP grade sits at 99-100%. Everyday lab work and classroom experiments are what it suits. On price, it comes out cheaper. AR grade is purer, 99.5% or higher. When analytical work calls for exact numbers, that is the one to pick.
Q: What is the right way to store CP grade sodium acetate trihydrate?
A: A2: Close the package tight. A cool, dry warehouse with air flowing through works best. Damp air brings trouble. So do strong acids and oxidants. Keep them all away. Store it this way, and it stays stable for a long time.
Q: Can this CP grade product be used for food processing?
A: A3: This product is only applicable for laboratory and industrial research scenarios. For food-grade applications, please consult us for qualified food-grade products.
Q: What is your standard order lead time?
A: A4: Standard orders are delivered within 7-10 working days. The delivery time of bulk orders will be confirmed according to the actual quantity and production schedule.
Q: Will COA documents come with every shipment?
A: A5: Yes. Every batch goes out with a full COA report. That report lists all test indicators. So you can review quality and track each batch.
Q: Can orders be shipped to other countries?
A: A6: Sure. We have rich export experience in Europe, America, Asia and other regions, with complete logistics and customs clearance documents.
