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 4-Methyl-3,4-dihydro-2H-[1,4]oxazino[2,3-f]isoquinolin-7(8H)-one.
4-Methyl-3,4-dihydro-2H-[1,4]oxazino[2,3-f]isoquinolin-7(8H)-one (CAS 1409950-15-7) is a high-purity analytical reference standard with the molecular formula C12H12N2O2 and a molecular weight of 216.24 g/mol.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 4-Methyl-3,4-dihydro-2H-[1,4]oxazino[2,3-f]isoquinolin-7(8H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 216.24 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), 4-Methyl-3,4-dihydro-2H-[1,4]oxazino[2,3-f]isoquinolin-7(8H)-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.
