Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (S)-9a-(4-chlorophenyl)-8-phenyl-9,9a-dihydropyrido[1,2-a]indole-6,10-dione.
(S)-9a-(4-chlorophenyl)-8-phenyl-9,9a-dihydropyrido[1,2-a]indole-6,10-dione (CAS 2368851-99-2), molecular formula C24H16ClNO2 and molecular weight 385.84 g/mol, is a CATO reference standard with documented purity and traceability.
(S)-9a-(4-chlorophenyl)-8-phenyl-9,9a-dihydropyrido[1,2-a]indole-6,10-dione (C24H16ClNO2) contains a steroid core, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), (S)-9a-(4-chlorophenyl)-8-phenyl-9,9a-dihydropyrido[1,2-a]indole-6,10-dione 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.
