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 Ethyl 1-(4-amino-1,2,5-oxadiazol-3-yl)-5-(((6-ethoxybenzo[d]thiazol-2-yl)thio)methyl)-1H-1,2,3-triazole-4-carboxylate.
Ethyl 1-(4-amino-1,2,5-oxadiazol-3-yl)-5-(((6-ethoxybenzo[d]thiazol-2-yl)thio)methyl)-1H-1,2,3-triazole-4-carboxylate (CAS 312499-48-2), molecular formula C17H17N7O4S2 and molecular weight 447.49 g/mol, is a CATO reference standard with documented purity and traceability.
Ethyl 1-(4-amino-1,2,5-oxadiazol-3-yl)-5-(((6-ethoxybenzo[d]thiazol-2-yl)thio)methyl)-1H-1,2,3-triazole-4-carboxylate (C17H17N7O4S2) 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.
