What is Thiamine Hydrochloride Powder CAS 67-03-8?

Thiamine Hydrochloride is the hydrochloride salt of vitamin B1, identified by CAS 67-03-8, EC number 200-641-8, and molecular formula C12H17ClN4OS.HCl. It is also called thiamine HCl or vitamin B1 hydrochloride and is normally supplied as a white crystalline or white powder.

How is Thiamine HCl different from vitamin B1?

Vitamin B1 is the general nutrient name, while thiamine hydrochloride is a specific stable salt form 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.

Which grades are available for Thiamine Hydrochloride Powder?

Common grades include food grade, feed grade, pharmaceutical grade, and nutritional or premix grade. The appropriate grade depends on the finished product, target market, pharmacopoeia or regulatory standard, required assay, residual solvent profile, and microbial limits.

What are the key specifications for CAS 67-03-8?

Important controls include appearance, assay or thiamine hydrochloride content, pH, loss on drying, residue on ignition, heavy metals, related substances, and particle size if required. The current listing states a molecular weight of 337.27, a melting point of 250 C with decomposition, and solubility in water.

How should Thiamine Hydrochloride be stored and handled?

Store it in a tightly closed, light-protective container in a cool, dry, well-ventilated area, and avoid unnecessary heat, moisture, and strong oxidizing agents. Confirm the offered package size, inner liner, lot traceability, storage temperature, and transport requirements before dispatch.

Applications

Thiamine Hydrochloride Powder is generally used as a vitamin B1 raw material in regulated or specification-based supply chains. Actual suitability depends on grade, formulation system, applicable standard, and end-use validation.

Typical application directions may include:

nutritional or dietary supplement formulations, depending on grade and regulatory requirements
pharmaceutical or healthcare raw material programs, subject to applicable standards and validation
food or beverage fortification systems, depending on local compliance requirements
feed or premix formulations, subject to grade confirmation and formulation review
laboratory or research use, depending on the offered grade

Any specific formulation use should be confirmed according to application requirements.

In vitamin-premix or fortification work where another water-soluble vitamin is specified, Vitamin B6 is a separate raw material with its own grade and regulatory requirements.

Packaging and Storage

Standard packaging is available. The product may be packed in bags, drums, cartons, or other suitable containers as applicable to the offered grade and supply format. Customized packaging may be available upon request.

Store in a tightly closed container in a dry place, protected from light and moisture. Storage conditions should be aligned with the offered grade and applicable product documentation.
