Chemical Structure
Description
(R)-tert-Butyl 5-methyl-4-((R)-1-methyl-2-oxo-1,2,3,5-tetrahydrobenzo[5,6][1,4]oxazino[3,4-c][1,2,4]triazin-9-yl)-5,6-dihydropyridine-1(2H)-carboxylate (CAS 1613722-44-3) is a high-purity analytical reference standard with the molecular formula C22H28N4O4 and a molecular weight of 412.48 g/mol.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, (R)-tert-Butyl 5-methyl-4-((R)-1-methyl-2-oxo-1,2,3,5-tetrahydrobenzo[5,6][1,4]oxazino[3,4-c][1,2,4]triazin-9-yl)-5,6-dihydropyridine-1(2H)-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 412.48 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.
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), (R)-tert-Butyl 5-methyl-4-((R)-1-methyl-2-oxo-1,2,3,5-tetrahydrobenzo[5,6][1,4]oxazino[3,4-c][1,2,4]triazin-9-yl)-5,6-dihydropyridine-1(2H)-carboxylate 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.
