2-((3-Chloro-4-fluorophenyl)amino)-4H-[1,3]thiazino[5,6-b]quinoxalin-4-one CAS 154371-22-9

Description

2-((3-Chloro-4-fluorophenyl)amino)-4H-[1,3]thiazino[5,6-b]quinoxalin-4-one (CAS 154371-22-9), molecular formula C16H8ClFN4OS and molecular weight 358.78 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 2-((3-Chloro-4-fluorophenyl)amino)-4H-[1,3]thiazino[5,6-b]quinoxalin-4-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 358.78 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.
