Chemical Structure

2-Chloro-5-fluoropyrimidine CAS 62802-42-0 chemical structure

Description

2-Chloro-5-fluoropyrimidine (CAS 62802-42-0) is a high-purity analytical reference standard with the molecular formula C4H2ClFN2 and a molecular weight of 132.52 g/mol.

Owing to a nitrile group, fluorine/chlorine substitution, 2-Chloro-5-fluoropyrimidine is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 132.52 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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 2-Chloro-5-fluoropyrimidine 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.
