    Sodium Acetate Anhydrous CAS 127-09-3

    Sodium Acetate Anhydrous (CAS 127-09-3), chemically identified as the sodium salt of acetic acid, is a hygroscopic organic salt functioning as a critical buffering agent and neutralization medium in textile dyeing operations and food preservation. This white crystalline powder, technically referred to as sodium ethanoate, acts to maintain precise pH levels in acid baths, preventing the premature precipitation of aniline dyes, and serves as a flavoring agent (E262) imparting the characteristic "salt and vinegar" taste in snack foods. We provide bulk supply of this high-purity industrial ingredient with competitive factory pricing to ensure process stability for textile mills and food processors. Our production guarantees low heavy metal content and high assay (>99%), making MSDS, TDS, COA available alongside customized specifications to meet technical or food grade requirements.

    If you have a special application (e.g. pharmaceutical, high-purity analytical grade or specific impurity limits), please send your detailed requirement to info@industrochem.com so we can match the right grade and specification.

    Storage Conditions

    • Store in a cool, dry and well-ventilated warehouse.
    • Keep bags tightly closed to avoid moisture absorption and caking.
    • Avoid direct sunlight and keep away from heat sources.
    • Store separately from strong acids and strong oxidizing agents.
    • Recommended shelf life: 24 months from production date in unopened original packaging.

    Safety Precautions

    • Sodium acetate is generally considered of low acute toxicity, but dust may cause slight irritation.
    • Avoid inhalation of dust and contact with eyes or prolonged skin contact.
    • Wear appropriate PPE during handling: dust mask or respirator, safety glasses and gloves.
    • In case of contact with eyes, rinse immediately with plenty of water and seek medical advice if irritation persists.
    • Avoid eating, drinking or smoking while handling the product; wash hands thoroughly after use.
    • For detailed hazard information, please refer to the product Safety Data Sheet (SDS).

    FAQ - Technical & Supply Chain

    • Q:

      Why is the anhydrous form (CAS 127-09-3) often preferred over the trihydrate form in industrial chemical synthesis?

      A: The anhydrous variant offers a significantly higher concentration of active acetate ions per unit of weight and does not introduce water into the reaction matrix, which is crucial for moisture-sensitive organic reactions where the presence of water molecules from the trihydrate crystal lattice could interfere with the yield or catalyze unwanted side reactions.
    • Q:

      In textile processing, what specific role does this salt play during the neutralization of waste sulfuric acid streams?

      A: Sodium Acetate acts as a mild conjugate base that neutralizes strong mineral acids like sulfuric acid more gently than caustic soda, effectively buffering the wastewater to a safe pH range without causing rapid temperature spikes or excessive alkalinity that could damage downstream biological treatment systems.
