Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-[(ethylamino)methyl]-3,4-dihydroquinazolin-4-one.
CATO supplies 2-[(ethylamino)methyl]-3,4-dihydroquinazolin-4-one (CAS 143993-13-9), a certified reference material (molecular formula C11H21N3O, MW 211.30 g/mol) for analytical method development and quality control.
Owing to an amide group, a hydroxyl group, an ether linkage, 2-[(ethylamino)methyl]-3,4-dihydroquinazolin-4-one is typically white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 211.30 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.
CATO manufactures 2-[(ethylamino)methyl]-3,4-dihydroquinazolin-4-one 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.
