Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Amino-4-(3-bromo-4-hydroxy-5-methoxyphenyl)-4H-benzo[h]chromene-3-carbonitrile.
2-Amino-4-(3-bromo-4-hydroxy-5-methoxyphenyl)-4H-benzo[h]chromene-3-carbonitrile (CAS 332053-47-1), molecular formula C21H15BrN2O3 and molecular weight 423.26 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Amino-4-(3-bromo-4-hydroxy-5-methoxyphenyl)-4H-benzo[h]chromene-3-carbonitrile (C21H15BrN2O3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
