Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Methyl 7-benzyl-5,8-dioxo-hexahydro-1H-[1,3]thiazolo[3,4-a]pyrazine-3-carboxylate.
Methyl 7-benzyl-5,8-dioxo-hexahydro-1H-[1,3]thiazolo[3,4-a]pyrazine-3-carboxylate (CAS 155266-96-9), molecular formula C15H16N2O4S and molecular weight 320.36 g/mol, is a CATO reference standard with documented purity and traceability.
Methyl 7-benzyl-5,8-dioxo-hexahydro-1H-[1,3]thiazolo[3,4-a]pyrazine-3-carboxylate (C15H16N2O4S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
