    Thiamine Hydrochloride Powder (Vitamin B1 HCl) CAS 67-03-8 is the hydrochloride salt of thiamine (vitamin B1) with the molecular formula C12H17ClN4OS·HCl and EINECS 200-641-8.

    Synonyms: Thiamine hydrochloride; Thiamine HCl; Aneurin hydrochloride; Vitamin B1 hydrochloride.

    CAS: 67-03-8.

    Molecular formula: C12H17ClN4OS·HCl.

    It is normally supplied as a white crystalline or white powder with a molecular weight of about 337.27.

    Thiamine hydrochloride is a stable hydrochloride salt form of vitamin B1 commonly used in food, feed, supplement, and pharmaceutical raw-material supply chains.

    Other thiamine salts, such as thiamine mononitrate, are separate materials with different CAS numbers and specification profiles.

    In food and beverage fortification it is used as a vitamin B1 source, subject to local compliance requirements.

    In pharmaceutical and healthcare raw-material programs it is used according to pharmacopoeia standards and validation.

    In feed and premix formulations it is used as a vitamin B1 source, subject to grade confirmation and formulation review.

    In nutritional and dietary supplement formulations it is used depending on grade and regulatory requirements.

    It is also used in laboratory or research applications depending on the offered grade.

    Store in a tightly closed, light-protective container in a cool, dry, well-ventilated area.

    Avoid unnecessary heat, moisture, and contact with strong oxidizing agents.

    Confirm the offered package size, inner liner, lot traceability, storage temperature, and transport requirements before dispatch, and follow the current SDS.

    Every batch is checked for appearance, assay/thiamine hydrochloride content, pH, loss on drying, residue on ignition, heavy metals, related substances, and particle size as required, with COA/TDS/SDS supplied per grade.

    Confirm assay, grade, particle size, packaging, and applicable pharmacopoeia or regulatory standard as required.
