Thiamine hydrochloride (Vitamin B1) is an essential micronutrient and a cofactor for many central metabolic enzymes.

Thiamine hydrochloride (Standard) is the analytical standard of Thiamine hydrochloride, primarily used for quantitative analysis and metabolic research. Thiamine hydrochloride (Vitamin B1 hydrochloride) is an essential micronutrient that serves as a vital cofactor for several central metabolic enzymes, including pyruvate dehydrogenase, α-ketoglutarate dehydrogenase, and transketolase. In vivo, it is phosphorylated into its active form, Thiamine Pyrophosphate (TPP), which is directly involved in carbohydrate metabolism, the TCA cycle, and the pentose phosphate pathway. It is indispensable for cellular energy production and the maintenance of nervous system integrity.
