Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 7-(2,3-dichlorophenyl)-7-oxoheptanoate.
Ethyl 7-(2,3-dichlorophenyl)-7-oxoheptanoate (CAS 898777-91-8), molecular formula C15H18Cl2O3 and molecular weight 317.21 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Ethyl 7-(2,3-dichlorophenyl)-7-oxoheptanoate (C15H18Cl2O3) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Ethyl 7-(2,3-dichlorophenyl)-7-oxoheptanoate 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.
