Description
As a certified reference material (CRM), 2,4-Dichloro-6-(7-methoxy-4,5-dihydropyrrolo[1,2-a]quinoxalin-4-yl)phenol 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.
CATO supplies 2,4-Dichloro-6-(7-methoxy-4,5-dihydropyrrolo[1,2-a]quinoxalin-4-yl)phenol (CAS 657350-29-3), a certified reference material (molecular formula C18H14Cl2N2O2, MW 361.22 g/mol) for analytical method development and quality control.
2,4-Dichloro-6-(7-methoxy-4,5-dihydropyrrolo[1,2-a]quinoxalin-4-yl)phenol (C18H14Cl2N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, 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 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.
