Chemical Structure

2-(Chloromethyl)pyridine CAS 4377-33-7 chemical structure

Description

CATO supplies 2-(Chloromethyl)pyridine (CAS 4377-33-7), a certified reference material (molecular formula C6H6ClN, MW 127.57 g/mol) for analytical method development and quality control.

Owing to a nitrile group, chlorine substitution, an aromatic ring system, 2-(Chloromethyl)pyridine is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 127.57 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-(Chloromethyl)pyridine 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.
