Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(3,5-Dimethoxyphenyl)-5-(((6-(p-tolyl)pyridazin-3-yl)thio)methyl)-1,2,4-oxadiazole.
CATO supplies 3-(3,5-Dimethoxyphenyl)-5-(((6-(p-tolyl)pyridazin-3-yl)thio)methyl)-1,2,4-oxadiazole (CAS 1111260-33-3), a certified reference material (molecular formula C22H20N4O3S, MW 420.48 g/mol) for analytical method development and quality control.
3-(3,5-Dimethoxyphenyl)-5-(((6-(p-tolyl)pyridazin-3-yl)thio)methyl)-1,2,4-oxadiazole (C22H20N4O3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
