CATO supplies 3-(7-Chloro-1-(methylthio)-5-oxo-[1,2,4]triazolo[4,3-a]quinazolin-4(5H)-yl)-N-isopropylpropanamide (CAS 1115967-07-1), a certified reference material (molecular formula C16H18ClN5O2S, MW 379.86 g/mol) for analytical method development and quality control.
The molecular framework of 3-(7-Chloro-1-(methylthio)-5-oxo-[1,2,4]triazolo[4,3-a]quinazolin-4(5H)-yl)-N-isopropylpropanamide (C16H18ClN5O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
