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.
5-Bromo-4-chloro-6-(4-fluorophenyl)thieno[2,3-d]pyrimidine (CAS 1799610-96-0) is a high-purity analytical reference standard with the molecular formula C12H5BrClFN2S and a molecular weight of 343.60 g/mol.
The molecular framework of 5-Bromo-4-chloro-6-(4-fluorophenyl)thieno[2,3-d]pyrimidine (C12H5BrClFN2S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine/chlorine/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.
CATO manufactures 5-Bromo-4-chloro-6-(4-fluorophenyl)thieno[2,3-d]pyrimidine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
