Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 4-Amino-3-cycloheptyl-6,7-dimethoxyquinazoline-2(3H)-thione (CAS 477848-87-6), a certified reference material (molecular formula C17H23N3O2S, MW 333.45 g/mol) for analytical method development and quality control.
The molecular framework of 4-Amino-3-cycloheptyl-6,7-dimethoxyquinazoline-2(3H)-thione (C17H23N3O2S) is characterized by a steroid core, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), 4-Amino-3-cycloheptyl-6,7-dimethoxyquinazoline-2(3H)-thione 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.
