Chemical Structure
Description
The occurrence of {2-[(4-bromophenyl)sulfanyl]pyridin-3-yl}methyl N-(2-methylphenyl)carbamate is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
{2-[(4-bromophenyl)sulfanyl]pyridin-3-yl}methyl N-(2-methylphenyl)carbamate (CAS 478031-21-9) is a high-purity analytical reference standard with the molecular formula C20H17BrN2O2S and a molecular weight of 429.33 g/mol.
The molecular framework of {2-[(4-bromophenyl)sulfanyl]pyridin-3-yl}methyl N-(2-methylphenyl)carbamate (C20H17BrN2O2S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), {2-[(4-bromophenyl)sulfanyl]pyridin-3-yl}methyl N-(2-methylphenyl)carbamate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
