Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4-[3-Nitro-4-(thiomorpholin-4-yl)phenyl]-1,2-dihydrophthalazin-1-one (CAS 882000-39-7) is a high-purity analytical reference standard with the molecular formula C18H16N4O3S and a molecular weight of 368.41 g/mol.
The molecular framework of 4-[3-Nitro-4-(thiomorpholin-4-yl)phenyl]-1,2-dihydrophthalazin-1-one (C18H16N4O3S) is characterized by a steroid core, an amide group, a sulfone 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).
CATO manufactures 4-[3-Nitro-4-(thiomorpholin-4-yl)phenyl]-1,2-dihydrophthalazin-1-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.
