Description
CATO supplies 7-(3-Fluorobenzyl)-3-methylisoxazolo[4,5-d]pyridazin-4(5H)-one (CAS 1361004-14-9), a certified reference material (molecular formula C13H10FN3O2, MW 259.24 g/mol) for analytical method development and quality control.
The molecular framework of 7-(3-Fluorobenzyl)-3-methylisoxazolo[4,5-d]pyridazin-4(5H)-one (C13H10FN3O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine 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. 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 7-(3-Fluorobenzyl)-3-methylisoxazolo[4,5-d]pyridazin-4(5H)-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.
