Description
3-Cyclopropyl-6-(4-((5,6,7,8-tetrahydronaphthalen-2-yl)sulfonyl)piperazin-1-yl)-[1,2,4]triazolo[4,3-b]pyridazine (CAS 1040641-42-6), molecular formula C22H26N6O2S and molecular weight 438.55 g/mol, is a CATO reference standard with documented purity and traceability.
3-Cyclopropyl-6-(4-((5,6,7,8-tetrahydronaphthalen-2-yl)sulfonyl)piperazin-1-yl)-[1,2,4]triazolo[4,3-b]pyridazine (C22H26N6O2S) 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.
