Chemical Structure

2-chloropentan-3-one CAS 17042-21-6 chemical structure

Description

Owing to a hydroxyl group, an ether linkage, chlorine substitution, 2-chloropentan-3-one is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 120.58 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.

2-chloropentan-3-one (CAS 17042-21-6) is a high-purity analytical reference standard with the molecular formula C5H9ClO and a molecular weight of 120.58 g/mol.

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-chloropentan-3-one 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.
