Description
CATO supplies 1,2,3',4'-Tetrahydro-1'H-spiro[indole-3,2'-quinazoline]-2-one (CAS 543745-35-3), a certified reference material (molecular formula C15H13N3O, MW 251.28 g/mol) for analytical method development and quality control.
1,2,3',4'-Tetrahydro-1'H-spiro[indole-3,2'-quinazoline]-2-one (C15H13N3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 1,2,3',4'-Tetrahydro-1'H-spiro[indole-3,2'-quinazoline]-2-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
