Chemical Structure
Description
The occurrence of 2-(Benzylimino)-N-(5-(m-tolyl)-1,3,4-thiadiazol-2-yl)-2H-chromene-3-carboxamide is closely related to a steroid core, 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.
2-(Benzylimino)-N-(5-(m-tolyl)-1,3,4-thiadiazol-2-yl)-2H-chromene-3-carboxamide (CAS 1261027-54-6), molecular formula C26H20N4O2S and molecular weight 452.53 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 2-(Benzylimino)-N-(5-(m-tolyl)-1,3,4-thiadiazol-2-yl)-2H-chromene-3-carboxamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 452.53 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
