Chemical Structure
Description
cis-2-(3-Methylbenzoyl)cyclopentane-1-carboxylic acid (CAS 732253-41-7), molecular formula C14H16O3 and molecular weight 232.28 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of cis-2-(3-Methylbenzoyl)cyclopentane-1-carboxylic acid (C14H16O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), cis-2-(3-Methylbenzoyl)cyclopentane-1-carboxylic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
