6-(3,5-Dibromo-2-hydroxy-4-methylphenyl)pyridazin-3(2H)-one (CAS 62902-45-8), molecular formula C11H8Br2N2O2 and molecular weight 360.00 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6-(3,5-Dibromo-2-hydroxy-4-methylphenyl)pyridazin-3(2H)-one (C11H8Br2N2O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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-(3,5-Dibromo-2-hydroxy-4-methylphenyl)pyridazin-3(2H)-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.
