Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6-((4,6-Dichloro-1,3,5-triazin-2-yl)amino)-3',6'-dihydroxy-3H-spiro[isobenzofuran-1,9'-xanthen]-3-one hydrochloride.
6-((4,6-Dichloro-1,3,5-triazin-2-yl)amino)-3',6'-dihydroxy-3H-spiro[isobenzofuran-1,9'-xanthen]-3-one hydrochloride (CAS 118357-32-7), molecular formula C23H12Cl2N4O5HCl and molecular weight 531.73 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6-((4,6-Dichloro-1,3,5-triazin-2-yl)amino)-3',6'-dihydroxy-3H-spiro[isobenzofuran-1,9'-xanthen]-3-one hydrochloride (C23H12Cl2N4O5HCl) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine 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. 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.
