Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (3β)-25-[Methyl(7-nitro-2,1,3-benzoxadiazol-4-yl)amino]-27-norcholest-5-en-3-ol.
CATO supplies (3β)-25-[Methyl(7-nitro-2,1,3-benzoxadiazol-4-yl)amino]-27-norcholest-5-en-3-ol (CAS 105539-27-3), a certified reference material (molecular formula C33H48N4O4, MW 564.76 g/mol) for analytical method development and quality control.
The molecular framework of (3β)-25-[Methyl(7-nitro-2,1,3-benzoxadiazol-4-yl)amino]-27-norcholest-5-en-3-ol (C33H48N4O4) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 (3β)-25-[Methyl(7-nitro-2,1,3-benzoxadiazol-4-yl)amino]-27-norcholest-5-en-3-ol 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.
