Chemical Structure
Description
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.
CATO supplies N-(5-((2-Amino-2-oxoethyl)thio)-1,3,4-thiadiazol-2-yl)-4-ethoxybenzamide (CAS 893150-73-7), a certified reference material (molecular formula C13H14N4O3S2, MW 338.41 g/mol) for analytical method development and quality control.
Structurally, N-(5-((2-Amino-2-oxoethyl)thio)-1,3,4-thiadiazol-2-yl)-4-ethoxybenzamide (C13H14N4O3S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 338.41 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
