Chemical Structure
Description
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.
Sulfachloropyridazine-13C6 (CAS 2731998-51-7) is a high-purity analytical reference standard with the molecular formula C4[13C]6H9ClN4O2S and a molecular weight of 290.68 g/mol.
Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, Sulfachloropyridazine-13C6 is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 290.68 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.
CATO manufactures Sulfachloropyridazine-13C6 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.
