Chemical Structure
Description
2712AF 5-Bromo-2,4-difluoropyrimidine 903131-29-3 C4HBrF2N2 (CAS 903131-29-3), molecular formula C4HBrF2N2 and molecular weight 194.96 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2712AF 5-Bromo-2,4-difluoropyrimidine 903131-29-3 C4HBrF2N2 (C4HBrF2N2) contains a nitrile group, fluorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 194.96 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
CATO manufactures 2712AF 5-Bromo-2,4-difluoropyrimidine 903131-29-3 C4HBrF2N2 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.
