Chemical Structure

2-Chloro-5-fluoropyridine 1-oxide CAS 405230-79-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 147.53 g/mol gives 2-Chloro-5-fluoropyridine 1-oxide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Chloro-5-fluoropyridine 1-oxide (CAS 405230-79-7), molecular formula C5H3ClFNO and molecular weight 147.53 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 2-Chloro-5-fluoropyridine 1-oxide is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 147.53 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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-fluoropyridine 1-oxide 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.
