Description
Compared with other compounds in its class, the molecular weight of 188.22 g/mol gives 5-Phenylcyclohexane-1,3-dione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-Phenylcyclohexane-1,3-dione (CAS 493-72-1), molecular formula C12H12O2 and molecular weight 188.22 g/mol, is a CATO reference standard with documented purity and traceability.
5-Phenylcyclohexane-1,3-dione (C12H12O2) 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 5-Phenylcyclohexane-1,3-dione 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.
