Chemical Structure
Description
As a certified reference material (CRM), Ethyl (1S,2S)-2-(4-methoxyphenyl)cyclopropane-1-carboxylate 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.
Ethyl (1S,2S)-2-(4-methoxyphenyl)cyclopropane-1-carboxylate (CAS 345905-97-7), molecular formula C13H16O3 and molecular weight 220.26 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Ethyl (1S,2S)-2-(4-methoxyphenyl)cyclopropane-1-carboxylate (C13H16O3) 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 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
