Description
As a certified reference material (CRM), 1-(4-Chlorophenyl)-6,7-dimethoxyisochroman-3-one 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.
1-(4-Chlorophenyl)-6,7-dimethoxyisochroman-3-one (CAS 167475-75-4) is a high-purity analytical reference standard with the molecular formula C17H15ClO4 and a molecular weight of 318.75 g/mol.
1-(4-Chlorophenyl)-6,7-dimethoxyisochroman-3-one (C17H15ClO4) contains a flavonoid core, a hydroxyl group, an ether linkage, chlorine substitution. 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.
