Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 8-Chloro-3,4-dihydronaphthalen-2(1H)-one.
8-Chloro-3,4-dihydronaphthalen-2(1H)-one (CAS 82302-27-0), molecular formula C10H9ClO and molecular weight 180.63 g/mol, is a CATO reference standard with documented purity and traceability.
8-Chloro-3,4-dihydronaphthalen-2(1H)-one (C10H9ClO) contains a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
As a certified reference material (CRM), 8-Chloro-3,4-dihydronaphthalen-2(1H)-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.
