Chemical Structure
Description
tert-Butyl 4-(3-ethyl-2,4-dioxo-1,2,3,4-tetrahydroquinazolin-6-yl)piperazine-1-carboxylate (CAS 1795300-50-3), molecular formula C19H26N4O4 and molecular weight 374.43 g/mol, is a CATO reference standard with documented purity and traceability.
tert-Butyl 4-(3-ethyl-2,4-dioxo-1,2,3,4-tetrahydroquinazolin-6-yl)piperazine-1-carboxylate (C19H26N4O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures tert-Butyl 4-(3-ethyl-2,4-dioxo-1,2,3,4-tetrahydroquinazolin-6-yl)piperazine-1-carboxylate 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.
