Description
Compared with other compounds in its class, the molecular weight of 385.24 g/mol gives 2-Ethyl-6-iodo-3-(2-(isopropylamino)ethyl)quinazolin-4(3H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Ethyl-6-iodo-3-(2-(isopropylamino)ethyl)quinazolin-4(3H)-one (CAS 77301-01-0) is a high-purity analytical reference standard with the molecular formula C15H20IN3O and a molecular weight of 385.24 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, iodine substitution, 2-Ethyl-6-iodo-3-(2-(isopropylamino)ethyl)quinazolin-4(3H)-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 385.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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-Ethyl-6-iodo-3-(2-(isopropylamino)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.
