Description
CATO manufactures 6-((3-Methoxyphenyl)sulfonyl)pyridazin-3-ol 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.
6-((3-Methoxyphenyl)sulfonyl)pyridazin-3-ol (CAS 1031990-88-1), molecular formula C11H10N2O4S and molecular weight 266.27 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 6-((3-Methoxyphenyl)sulfonyl)pyridazin-3-ol is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 266.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
