Chemical Structure
Description
As a certified reference material (CRM), 3-(2-methoxyethyl)quinazoline-2,4(1H,3H)-dione 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.
3-(2-methoxyethyl)quinazoline-2,4(1H,3H)-dione (CAS 77093-97-1) is a high-purity analytical reference standard with the molecular formula C11H12N2O3 and a molecular weight of 220.22 g/mol.
The molecular framework of 3-(2-methoxyethyl)quinazoline-2,4(1H,3H)-dione (C11H12N2O3) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
