Chemical Structure
Description
(1R,2R)-2-(3,5-dimethylbenzoyl)cyclohexane-1-carboxylic acid (CAS 733742-85-3), molecular formula C16H20O3 and molecular weight 260.33 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (1R,2R)-2-(3,5-dimethylbenzoyl)cyclohexane-1-carboxylic acid (C16H20O3) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), (1R,2R)-2-(3,5-dimethylbenzoyl)cyclohexane-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.
