Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(R)-6-((4-Fluorobenzyl)oxy)-2-nitro-6,7-dihydro-5H-imidazo[2,1-b][1,3]oxazine (CAS 187235-63-8) is a high-purity analytical reference standard with the molecular formula C13H12FN3O4 and a molecular weight of 293.25 g/mol.
(R)-6-((4-Fluorobenzyl)oxy)-2-nitro-6,7-dihydro-5H-imidazo[2,1-b][1,3]oxazine (C13H12FN3O4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), (R)-6-((4-Fluorobenzyl)oxy)-2-nitro-6,7-dihydro-5H-imidazo[2,1-b][1,3]oxazine 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.
