Chemical Structure
Description
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.
tert-Butyl (S)-5-bromo-4-(bromomethyl)-6-(2-chloro-4-fluorophenyl)-2-(thiazol-2-yl)pyrimidine-1(6H)-carboxylate (CAS 2067376-01-4) is a high-purity analytical reference standard with the molecular formula C19H17Br2ClFN3O2S and a molecular weight of 565.68 g/mol.
The molecular framework of tert-Butyl (S)-5-bromo-4-(bromomethyl)-6-(2-chloro-4-fluorophenyl)-2-(thiazol-2-yl)pyrimidine-1(6H)-carboxylate (C19H17Br2ClFN3O2S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine/bromine 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.
As a certified reference material (CRM), tert-Butyl (S)-5-bromo-4-(bromomethyl)-6-(2-chloro-4-fluorophenyl)-2-(thiazol-2-yl)pyrimidine-1(6H)-carboxylate 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.
