Chemical Structure
Description
CATO supplies 5-Chloro-2-ethylpyridine (CAS 1159815-12-9), a certified reference material (molecular formula C7H8ClN, MW 141.60 g/mol) for analytical method development and quality control.
Owing to a nitrile group, chlorine substitution, an aromatic ring system, 5-Chloro-2-ethylpyridine is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 141.60 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 5-Chloro-2-ethylpyridine 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.
