Chemical Structure

(1R,2S)-2-(3-chlorobenzoyl)cyclopentane-1-carboxylic acid CAS 733740-13-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 252.69 g/mol gives (1R,2S)-2-(3-chlorobenzoyl)cyclopentane-1-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(1R,2S)-2-(3-chlorobenzoyl)cyclopentane-1-carboxylic acid (CAS 733740-13-1) is a high-purity analytical reference standard with the molecular formula C13H13ClO3 and a molecular weight of 252.69 g/mol.

The molecular framework of (1R,2S)-2-(3-chlorobenzoyl)cyclopentane-1-carboxylic acid (C13H13ClO3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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 (1R,2S)-2-(3-chlorobenzoyl)cyclopentane-1-carboxylic acid 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.
