7-Ethoxy-4-methyl-N-(4,4,6-trimethyl-1,4-dihydropyrimidin-2-yl)quinazolin-2-amine CAS 309731-36-0 chemical structure

Description

The occurrence of 7-Ethoxy-4-methyl-N-(4,4,6-trimethyl-1,4-dihydropyrimidin-2-yl)quinazolin-2-amine is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

7-Ethoxy-4-methyl-N-(4,4,6-trimethyl-1,4-dihydropyrimidin-2-yl)quinazolin-2-amine (CAS 309731-36-0), molecular formula C18H23N5O and molecular weight 325.41 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 7-Ethoxy-4-methyl-N-(4,4,6-trimethyl-1,4-dihydropyrimidin-2-yl)quinazolin-2-amine (C18H23N5O) is characterized by a steroid core, an amide 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.

As a certified reference material (CRM), 7-Ethoxy-4-methyl-N-(4,4,6-trimethyl-1,4-dihydropyrimidin-2-yl)quinazolin-2-amine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
