Description
CATO supplies N-(4-bromophenyl)-3-((2,6-dichlorobenzyl)thio)thiophene-2-carboxamide (CAS 251097-43-5), a certified reference material (molecular formula C18H12BrCl2NOS2, MW 473.23 g/mol) for analytical method development and quality control.
Structurally, N-(4-bromophenyl)-3-((2,6-dichlorobenzyl)thio)thiophene-2-carboxamide (C18H12BrCl2NOS2) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 473.23 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
