Application

Thiamine monophosphate chloride dihydrate has been used as a standard in high-performance liquid chromatography (HPLC) to quantify thiamine in plant exudates and to evaluate its purity.

Biochem/physiol Actions

Thiamine monophosphate (TMP) is used as a substrate of thiamine-phosphate kinase (EC 2.7.4.16) and a precursor of thiamine pyrophosphate (TPP). TPP is a coenzyme involved in the catabolism of sugars and amino acids.
