3-Ethoxy-1-ethyl-N-(5-mercapto-1,3,4-thiadiazol-2-yl)-1h-pyrazole-4-carboxamide CAS 1172334-53-0

Description

The occurrence of 3-Ethoxy-1-ethyl-N-(5-mercapto-1,3,4-thiadiazol-2-yl)-1h-pyrazole-4-carboxamide is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-Ethoxy-1-ethyl-N-(5-mercapto-1,3,4-thiadiazol-2-yl)-1h-pyrazole-4-carboxamide (CAS 1172334-53-0) is a high-purity analytical reference standard with the molecular formula C10H13N5O2S2 and a molecular weight of 299.37 g/mol.

3-Ethoxy-1-ethyl-N-(5-mercapto-1,3,4-thiadiazol-2-yl)-1h-pyrazole-4-carboxamide (C10H13N5O2S2) contains a nitrogen-containing heterocyclic scaffold, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
