Chemical Structure
Description
As a certified reference material (CRM), 2-(Hydroxymethyl)-N-methyl-2,3-dihydro-1H-benzo[f]chromen-1-aminium chloride 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.
2-(Hydroxymethyl)-N-methyl-2,3-dihydro-1H-benzo[f]chromen-1-aminium chloride (CAS 477708-75-1), molecular formula C15H18NO2Cl and molecular weight 279.76 g/mol, is a CATO reference standard with documented purity and traceability.
2-(Hydroxymethyl)-N-methyl-2,3-dihydro-1H-benzo[f]chromen-1-aminium chloride (C15H18NO2Cl) contains a nitrogen-containing heterocyclic scaffold, an amide group, 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.
