CATO supplies 5-Bromo-3,4-dimethylthieno[2,3-c]pyridazine-6-carbonitrile (CAS 1639210-89-1), a certified reference material (molecular formula C9H6BrN3S, MW 268.13 g/mol) for analytical method development and quality control.
5-Bromo-3,4-dimethylthieno[2,3-c]pyridazine-6-carbonitrile (C9H6BrN3S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
CATO manufactures 5-Bromo-3,4-dimethylthieno[2,3-c]pyridazine-6-carbonitrile 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.
