Description
Compared with other compounds in its class, the molecular weight of 216.23 g/mol gives 2-(5-Oxo-2-phenylcyclopent-1-en-1-yl)acetic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-(5-Oxo-2-phenylcyclopent-1-en-1-yl)acetic acid (CAS 42882-19-9) is a high-purity analytical reference standard with the molecular formula C13H12O3 and a molecular weight of 216.23 g/mol.
The molecular framework of 2-(5-Oxo-2-phenylcyclopent-1-en-1-yl)acetic acid (C13H12O3) 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).
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 2-(5-Oxo-2-phenylcyclopent-1-en-1-yl)acetic 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.
