5-(Benzo[d]thiazol-2-yl)-N-(4-methoxyphenyl)thiophene-2-carboxamide CAS 622345-01-1

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-(Benzo[d]thiazol-2-yl)-N-(4-methoxyphenyl)thiophene-2-carboxamide.

5-(Benzo[d]thiazol-2-yl)-N-(4-methoxyphenyl)thiophene-2-carboxamide (CAS 622345-01-1), molecular formula C19H14N2O2S2 and molecular weight 366.46 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 5-(Benzo[d]thiazol-2-yl)-N-(4-methoxyphenyl)thiophene-2-carboxamide (C19H14N2O2S2) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 366.46 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
