CATO supplies 6-CHLORO-3H-PYRIMIDO[4,5-B]INDOL-4(9H)-ONE (CAS 1403589-25-2), a certified reference material (molecular formula C10H6ClN3O, MW 219.63 g/mol) for analytical method development and quality control.
6-CHLORO-3H-PYRIMIDO[4,5-B]INDOL-4(9H)-ONE (C10H6ClN3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
