Chemical Structure
Description
The occurrence of 7-chloro-3-methyl-isoxazolo[4,5-d]pyridazine is closely related to an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 7-chloro-3-methyl-isoxazolo[4,5-d]pyridazine (CAS 106584-76-3), a certified reference material (molecular formula C6H12ClN3O, MW 177.63 g/mol) for analytical method development and quality control.
The molecular framework of 7-chloro-3-methyl-isoxazolo[4,5-d]pyridazine (C6H12ClN3O) is characterized by an amide group, a hydroxyl group, an ether linkage, chlorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
As a certified reference material (CRM), 7-chloro-3-methyl-isoxazolo[4,5-d]pyridazine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
