Chemical Structure
Description
1-(Ethoxycarbonyl)-3-cyclopentene-1-carboxylic Acid (CAS 76910-08-2), molecular formula C9H12O4 and molecular weight 184.19 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(Ethoxycarbonyl)-3-cyclopentene-1-carboxylic Acid (C9H12O4) 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 the polarity and ionization state of its functional groups, 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).
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 1-(Ethoxycarbonyl)-3-cyclopentene-1-carboxylic Acid 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.
