tert-Butyl 4-(3-(2-ethoxy-2-oxoethyl)-4-oxo-3,4-dihydroquinazolin-6-yl)piperazine-1-carboxylate CAS 183622-37-9 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including tert-Butyl 4-(3-(2-ethoxy-2-oxoethyl)-4-oxo-3,4-dihydroquinazolin-6-yl)piperazine-1-carboxylate.

CATO supplies tert-Butyl 4-(3-(2-ethoxy-2-oxoethyl)-4-oxo-3,4-dihydroquinazolin-6-yl)piperazine-1-carboxylate (CAS 183622-37-9), a certified reference material (molecular formula C21H28N4O5, MW 416.47 g/mol) for analytical method development and quality control.

The molecular framework of tert-Butyl 4-(3-(2-ethoxy-2-oxoethyl)-4-oxo-3,4-dihydroquinazolin-6-yl)piperazine-1-carboxylate (C21H28N4O5) is characterized by a flavonoid 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
