Chemical Structure
Description
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.
(E)-4-Cyano-N-(4-ethoxy-3-ethylbenzo[d]thiazol-2(3H)-ylidene)benzamide (CAS 864925-45-1) is a high-purity analytical reference standard with the molecular formula C19H17N3O2S and a molecular weight of 351.42 g/mol.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, (E)-4-Cyano-N-(4-ethoxy-3-ethylbenzo[d]thiazol-2(3H)-ylidene)benzamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 351.42 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
