Chemical Structure

trans-2-(4-Fluoro-phenyl)-cyclopropanecarboxylic acid ethyl ester CAS 70461-58-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including trans-2-(4-Fluoro-phenyl)-cyclopropanecarboxylic acid ethyl ester.

trans-2-(4-Fluoro-phenyl)-cyclopropanecarboxylic acid ethyl ester (CAS 70461-58-4), molecular formula C12H13FO2 and molecular weight 208.23 g/mol, is a CATO reference standard with documented purity and traceability.

trans-2-(4-Fluoro-phenyl)-cyclopropanecarboxylic acid ethyl ester (C12H13FO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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 trans-2-(4-Fluoro-phenyl)-cyclopropanecarboxylic acid ethyl ester 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.
