- Product Description
USP Grade Potassium Acetate for Pharmaceutical Manufacturing: Premium Quality Buffering & pH Control Solution
SHANXI ZHAOYI CHEMICAL CO., LTD. has been producing acetate chemicals since 1988. That gives us more than 37 years of production experience. Our yearly acetate output holds at 150,000 tons, and the production plant covers a standardized 27,000 m². We focus on high-purity pharmaceutical excipients for drug companies worldwide. Our USP Grade Potassium Acetate (CAS 127-08-2) is a white crystalline powder. We make it to match USP pharmacopeia standards exactly. ISO certification is in place. KOSHER and HALAL approvals are held too. Its chemical formula is CH3COOK. Molecular weight comes to 98.14 g/mol. Drug makers use it widely in formulations that meet regulations. Shipments go out all the time to mainst
ream markets in Europe, America, and Asia, backed by established quality control systems. It works as a reliable bioavailable potassium source and a skilled pH buffering agent.

Key Features & Benefits
Our this product is made for drug production and compounding jobs. It has tight quality specs and a range of functions. Drug makers use it to keep product quality steady. It also helps them meet regulatory standards. Formulation results get better too:
- Strict Pharmacopeial Compliance: The product satisfies the access requirements of international pharmaceutical raw materials and completely complies with the most recent USP monograph standards. A professional Certificate of Analysis is provided for each independent production batch in order to facilitate client product registration and quality assessment.
- Ultrahigh & steady Purity: A uniform crystal structure comes from precision crystallization and impurity removal technology. That is why the material performs the same way every time. In mass production, batch-to-batch quality differences fall away. The pH buffering effect also stays steady across many pH-sensitive pharmaceutical formulae.
- Bioavailability: Set this acetate salt beside standard potassium chloride raw materials and it absorbs better, with less irritation in the gut. Safety goes up for drugs taken by mouth or given by IV, and patients tolerate them better.
- Strong Formulation Compatibility: This product suits a wide range of uses. It works with injectable solutions, oral liquids, compounding work, and other preparation methods. Raw material purchasing gets simpler too, and more pharmaceutical product line layouts become possible.
- Ultra-Low Contaminant Residue: Traces of harmful contaminants stay under tight control. Multi-stage filtration does the fine work, and heavy metals get taken out along the way. Possible safety problems for patients never make it through. Brand image holds up as a result, and long-term compliance credentials stay intact.

How It Works
This product works off a steady weak acid buffer system. Its ions split apart easily in liquid. Those two traits together bring exact pH control and nutrition support to drug formulations. The tough demands of drug production and storage are met without trouble:
Stable pH Buffering Mechanism: Once it dissolves in an aqueous solution, acetate ions and acetic acid pair up into a balanced buffer system. Temperature swings from outside and reactions between raw materials can push pH around. This system holds the line against those shifts. So pH values of drug products stay steady while you make them and while they sit in storage.
Efficient Electrolyte Supplement: Drop it in water and it breaks apart fully. That frees active potassium cations, which the body takes in and puts to work with very little loss. Acetate anions also take part in normal cell metabolism. The result is electrolyte support that is safe and works well.
Dual-Function Formula Optimization: In compounding work, this material does two jobs at once. It brings the pH to a physiological level, and it adds potassium as an electrolyte. One raw material carries out two core functions. Because of that, fewer auxiliary materials are needed in the formula, and the production process becomes simpler.
Applications
The product follows USP pharmacopeia rules. It is safe, and it works well alongside other ingredients. That is why it turns up so often in demanding pharmaceutical preparations and medical compounding work:
Injectable Solutions: A key helper material for IV infusion formulas. Those formulas need extra potassium. Their pH also has to stay steady. Production runs under tight pharma-grade rules. That way the material meets the sterility and purity demands of injection preparations.
Oral Liquid Medications: It goes into a wide range of medicinal syrups and suspensions. Two things happen there. Electrolyte levels inside the body get balanced, and the product tastes better. Patients find it easier to take their medicine, so they stick with it more often.
Dialysis Solutions: It acts as a main electrolyte part in peritoneal dialysis and hemodialysis fluids. The physiological ion concentration of those fluids stays stable because of it. That keeps renal replacement therapy safe and effective.
Pharmaceutical Compounding: A good fit for special pharmacies and hospitals that prepare medicines to order. Doses come out accurate, and each patient group can get its own formula.
Pharmaceutical Buffer Systems: Holds pH steady for antibiotic suspensions and vitamin preparations. Active ingredients fade away more slowly this way, so the product keeps longer on the shelf.

Manufacturing Process
We strictly select pharmaceutical-grade acetic acid and potassium hydroxide from certified qualified suppliers as raw materials, and all incoming materials will pass strict sampling testing before being put into production to eliminate source impurities.
Neutralization synthesis happens inside a closed precision reactor. Temperature and pH values are watched live and held tight the whole time. The reaction then runs far enough and stays steady, so the basic properties of the product come out the same.
Crystallization is only the first step. After that come several rounds of cleaning. Drying happens at low temperature, then micronization shapes the powder. Filtration runs in multiple stages and is very precise. Particulate impurities come out. So do abnormal crystals. What is left is powder with even particle size and solubility that holds steady.
Each finished batch goes through offline testing before anything else happens. Identity gets verified. Purity is measured, and heavy metals are screened. Only batches that fully meet USP standards are released and delivered. That is how we keep 100% qualified pharmaceutical-grade quality.
