Chemical Structure
Description
CATO supplies 2-((3-(3-Fluorophenyl)-[1,2,4]triazolo[4,3-b]pyridazin-6-yl)thio)-N-(o-tolyl)acetamide (CAS 852374-55-1), a certified reference material (molecular formula C20H16FN5OS, MW 393.44 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, 2-((3-(3-Fluorophenyl)-[1,2,4]triazolo[4,3-b]pyridazin-6-yl)thio)-N-(o-tolyl)acetamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 393.44 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.
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.
