2-((2,5-Dimethyl-1-(pyridin-2-yl)-1H-pyrrol-3-yl)methylene)benzo[4,5]imidazo[2,1-b]thiazol-3(2H)-one CAS 444180-85-2 chemical structure

Description

Structurally, 2-((2,5-Dimethyl-1-(pyridin-2-yl)-1H-pyrrol-3-yl)methylene)benzo[4,5]imidazo[2,1-b]thiazol-3(2H)-one (C21H16N4OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 16.0, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 372.44 g/mol, it falls into the moderately-high-molecular-weight range. 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).

2-((2,5-Dimethyl-1-(pyridin-2-yl)-1H-pyrrol-3-yl)methylene)benzo[4,5]imidazo[2,1-b]thiazol-3(2H)-one (CAS 444180-85-2), molecular formula C21H16N4OS and molecular weight 372.44 g/mol, is a CATO reference standard with documented purity and traceability.

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.
