What is Sodium Acetate Anhydrous CAS 127-09-3?

Sodium acetate anhydrous is the water-free sodium salt of acetic acid. It is a white crystalline or granular powder used as a buffer, food additive, synthesis reagent and industrial processing aid.

Why choose the anhydrous form instead of sodium acetate trihydrate?

The anhydrous form contains more acetate per unit weight and introduces no water of crystallization. It is preferred in moisture-sensitive reactions, non-aqueous systems and applications where a higher active concentration is required.

Why is sodium acetate used for neutralizing strong acid streams?

Sodium acetate is a mild base and conjugate base of acetic acid. It neutralizes strong mineral acids more gently than concentrated caustic soda and helps maintain a controlled pH, which is useful in textile and finishing processes.

Is this product suitable for food use?

The standard listing is industrial grade with assay at least 99.0%. Food/FCC grade is available on request, and the intended food application should be confirmed with the supplier along with the appropriate grade and documentation.

Which packaging is available?

It is supplied in 25 kg PP woven bags with a PE inner liner, with 500-1000 kg jumbo bags or customized packaging available on request.

What specifications should be checked before ordering?

Confirm grade, assay, water, pH, chloride, sulfate, heavy metals, free alkali and any food-grade or microbial requirements. Request the current batch analysis, technical data and safety information before purchase.

How should sodium acetate anhydrous be stored and handled?

Store in tightly closed containers in a cool, dry, ventilated area away from moisture, strong oxidizers and incompatible materials. Use dust-control measures and suitable PPE, and follow the safety information for handling and disposal.

Product Description

Sodium Acetate Anhydrous, CAS 127-09-3, also known as sodium ethanoate or acetic acid sodium salt, is the anhydrous sodium salt of acetic acid; the EC/EINECS number is 204-823-8.

Synonyms: sodium ethanoate; acetic acid sodium salt; anhydrous sodium acetate; natrium aceticum; sodium acetate powder.

CAS: 127-09-3.

Molecular formula: C₂H₃NaO₂.

Molecular weight: 82.03 g/mol.

EC number: 204-823-8.

It is a white, free-flowing crystalline powder with good solubility in water.

The assay (as CH₃COONa, dry basis) is ≥99.0%; a 5% aqueous solution at 25 °C has a pH of 8.5–9.5.

The true density at 20 °C is about 1.52–1.53 g/cm³; the melting point is about 324 °C.

It is used in pH buffering, food preservation and flavor systems.

It is used in pharmaceutical formulations, textile neutralization and dyeing, leather tanning and electroplating.

It is used in photography, water treatment and laboratory synthesis as a mild base and process auxiliary.

The anhydrous form contains more acetate per unit weight and is preferred in moisture-sensitive and non-aqueous systems.

Confirm grade, assay, water, pH, chloride, sulfate, heavy metals, free alkali and food-grade or microbial requirements.

Store in tightly closed containers in a cool, dry, ventilated area away from moisture, strong oxidizers and incompatible materials.

Confirm packaging with the requested quantity and destination requirements.

Document requirements should be confirmed from the current specification, SDS, COA or other product-specific files.
