Chemical Structure
Description
The molecular framework of (1S,2S)-2-(o-tolyl)cyclopropane-1-carboxylic acid (C11H12O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
(1S,2S)-2-(o-tolyl)cyclopropane-1-carboxylic acid (CAS 705250-88-0), molecular formula C11H12O2 and molecular weight 176.21 g/mol, is a CATO reference standard with documented purity and traceability.
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), (1S,2S)-2-(o-tolyl)cyclopropane-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.
