Description
Compared with other compounds in its class, the molecular weight of 437.90 g/mol gives Phenyl 2-((2-((4-chlorophenyl)amino)-2-oxoethyl)thio)-1H-benzo[d]imidazole-1-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Phenyl 2-((2-((4-chlorophenyl)amino)-2-oxoethyl)thio)-1H-benzo[d]imidazole-1-carboxylate (CAS 845879-37-0) is a high-purity analytical reference standard with the molecular formula C22H16ClN3O3S and a molecular weight of 437.90 g/mol.
The molecular framework of Phenyl 2-((2-((4-chlorophenyl)amino)-2-oxoethyl)thio)-1H-benzo[d]imidazole-1-carboxylate (C22H16ClN3O3S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
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.
