Description

Sodium Acetate Hydrate is a versatile and widely used sodium salt of acetic acid, commonly supplied in its trihydrate form. This compound is valued for its role as a reliable buffer, pH adjuster, and source of acetate ions across diverse industrial and laboratory processes. Key industries that utilize this product include pharmaceuticals, food processing, biotechnology, and textile manufacturing, where consistent quality and purity are paramount.

Application

• Pharmaceutical Buffer & Excipient: Used in dialysis solutions, intravenous formulations, and as a buffering agent in various drug products to maintain stable pH.
• Food Additive (E262): Acts as a preservative, acidity regulator, and flavoring agent in processed foods and snacks.
• Molecular Biology & Biochemistry: A key component in nucleic acid purification protocols (e.g., ethanol precipitation) and as a buffer in enzymatic reactions.
• Textile Industry: Employed as a photoresist in dyeing processes and as a neutralizing agent for sulfuric acid waste streams.
• Heat Storage & Hand Warmers: Utilized in phase-change material (PCM) applications due to its ability to release latent heat upon crystallization from a supercooled state.
• Industrial Chemical Synthesis: Serves as a precursor or catalyst in the production of various chemicals, including dyes and synthetic flavors.
• Concrete Additive: Used as a non-chloride accelerator to reduce setting time in cold weather concreting applications.
• Laboratory Reagent: A common reagent for analytical chemistry, buffer preparation, and general research purposes.

Quality Control

Our Sodium Acetate Hydrate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets the required specifications for purity, identity, and performance. Certificates of Analysis (COA) are provided with each shipment and are available upon request. We can supply material compliant with various pharmacopeial standards (USP, Ph. Eur., BP, JP) and food-grade specifications (FCC) to meet your specific application needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and must be kept in its original, sealed packaging until use to prevent caking and degradation due to moisture absorption.
