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 2-(1-(Phenethylamino)ethyl)quinazolin-4(3H)-one.
2-(1-(Phenethylamino)ethyl)quinazolin-4(3H)-one (CAS 143993-21-9) is a high-purity analytical reference standard with the molecular formula C18H19N3O and a molecular weight of 293.36 g/mol.
The molecular framework of 2-(1-(Phenethylamino)ethyl)quinazolin-4(3H)-one (C18H19N3O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-(1-(Phenethylamino)ethyl)quinazolin-4(3H)-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
