Chemical Structure

5350-67-4 AR-1J0331 ethyl(6-chloro-2-methyl-4-oxoquinazolin-3(4h)-yl)acetate CAS 5350-67-4 chemical structure

Description

5350-67-4 AR-1J0331 ethyl(6-chloro-2-methyl-4-oxoquinazolin-3(4h)-yl)acetate (CAS 5350-67-4), molecular formula C5H10N2 and molecular weight 98.15 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrile group, 5350-67-4 AR-1J0331 ethyl(6-chloro-2-methyl-4-oxoquinazolin-3(4h)-yl)acetate is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 98.15 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

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.
