Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6,12-Diphenyl-10-thia-1,5,6,8-tetraazatricyclo[7.3.0.0^{3,7}]dodeca-3(7),4,8,11-tetraen-2-one.
6,12-Diphenyl-10-thia-1,5,6,8-tetraazatricyclo[7.3.0.0^{3,7}]dodeca-3(7),4,8,11-tetraen-2-one (CAS 174535-76-3) is a high-purity analytical reference standard with the molecular formula C19H12N4OS and a molecular weight of 344.39 g/mol.
The molecular framework of 6,12-Diphenyl-10-thia-1,5,6,8-tetraazatricyclo[7.3.0.0^{3,7}]dodeca-3(7),4,8,11-tetraen-2-one (C19H12N4OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 6,12-Diphenyl-10-thia-1,5,6,8-tetraazatricyclo[7.3.0.0^{3,7}]dodeca-3(7),4,8,11-tetraen-2-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
