Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 262.34 g/mol gives Ethyl 7-oxo-7-(m-tolyl)heptanoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Ethyl 7-oxo-7-(m-tolyl)heptanoate (CAS 898751-54-7), a certified reference material (molecular formula C16H22O3, MW 262.34 g/mol) for analytical method development and quality control.
Ethyl 7-oxo-7-(m-tolyl)heptanoate (C16H22O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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-oxo-7-(m-tolyl)heptanoate 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.
