Ethyl 2-(((4-aminoquinazolin-2-yl)methyl)thio)acetate (CAS 1209765-68-3), molecular formula C13H15N3O2S and molecular weight 277.34 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Ethyl 2-(((4-aminoquinazolin-2-yl)methyl)thio)acetate (C13H15N3O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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.
