Chemical Structure

2-Butylcyclopentan-1-one CAS 934-42-9 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Butylcyclopentan-1-one.

2-Butylcyclopentan-1-one (CAS 934-42-9), molecular formula C9H16O and molecular weight 140.22 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a hydroxyl group, an ether linkage, 2-Butylcyclopentan-1-one is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 140.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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-Butylcyclopentan-1-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.
