Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Ethyl-2-(6-(N-phenylacetamido)hexa-1,3,5-trien-1-yl)benzo[d]oxazol-3-ium iodide.
3-Ethyl-2-(6-(N-phenylacetamido)hexa-1,3,5-trien-1-yl)benzo[d]oxazol-3-ium iodide (CAS 24136-83-2), molecular formula C23H23N2O2I and molecular weight 486.35 g/mol, is a CATO reference standard with documented purity and traceability.
3-Ethyl-2-(6-(N-phenylacetamido)hexa-1,3,5-trien-1-yl)benzo[d]oxazol-3-ium iodide (C23H23N2O2I) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, iodine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), 3-Ethyl-2-(6-(N-phenylacetamido)hexa-1,3,5-trien-1-yl)benzo[d]oxazol-3-ium iodide 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.
