Thiamine-d₃ hydrochloride（Cat No.:I044978）is a deuterium-labeled form of vitamin B1, with three hydrogen atoms replaced by deuterium for use in isotope tracing studies. As an essential cofactor in carbohydrate metabolism, thiamine plays a key role in enzymatic reactions such as pyruvate decarboxylation and the pentose phosphate pathway. The d₃-labeled variant enables precise quantification and kinetic analysis in LC-MS-based metabolomics, nutritional studies, and pharmacokinetics. Provided as a hydrochloride salt for enhanced stability and solubility, thiamine-d₃ hydrochloride is ideal for biomedical and biochemical research applications requiring high-resolution metabolic profiling.
