Chemical Structure

2-chlorocycloheptanone CAS 766-66-5 chemical structure

Description

CATO supplies 2-chlorocycloheptanone (CAS 766-66-5), a certified reference material (molecular formula C7H11ClO, MW 146.61 g/mol) for analytical method development and quality control.

Owing to a hydroxyl group, an ether linkage, chlorine substitution, 2-chlorocycloheptanone is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 146.61 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-chlorocycloheptanone 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.
