Ethyl 4-((2,4-diaminoquinazolin-6-yl)sulfonyl)piperazine-1-carboxylate CAS 92144-25-7

Description

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.

CATO supplies Ethyl 4-((2,4-diaminoquinazolin-6-yl)sulfonyl)piperazine-1-carboxylate (CAS 92144-25-7), a certified reference material (molecular formula C15H20N6O4S, MW 380.42 g/mol) for analytical method development and quality control.

Based on its molecular formula C15H20N6O4S, Ethyl 4-((2,4-diaminoquinazolin-6-yl)sulfonyl)piperazine-1-carboxylate contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 380.42 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
