Chemical Structure
Description
Ethyl 5-oxo-5-(3,4,5-trichlorophenyl)pentanoate (CAS 951887-53-9) is a high-purity analytical reference standard with the molecular formula C13H13Cl3O3 and a molecular weight of 323.60 g/mol.
The molecular framework of Ethyl 5-oxo-5-(3,4,5-trichlorophenyl)pentanoate (C13H13Cl3O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 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).
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), Ethyl 5-oxo-5-(3,4,5-trichlorophenyl)pentanoate 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.
