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 Ethyl 5-(3-chloro-4-methylphenyl)-5-oxopentanoate.
Ethyl 5-(3-chloro-4-methylphenyl)-5-oxopentanoate (CAS 951890-24-7), molecular formula C14H17ClO3 and molecular weight 268.74 g/mol, is a CATO reference standard with documented purity and traceability.
Ethyl 5-(3-chloro-4-methylphenyl)-5-oxopentanoate (C14H17ClO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. It is notably hygroscopic, 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 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.
CATO manufactures Ethyl 5-(3-chloro-4-methylphenyl)-5-oxopentanoate 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.
