Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
8-fluoro-2,3,4,5-tetrahydro-1,4-benzoxazepine (CAS 844648-13-1) is a high-purity analytical reference standard with the molecular formula C9H10FNO and a molecular weight of 167.18 g/mol.
8-fluoro-2,3,4,5-tetrahydro-1,4-benzoxazepine (C9H10FNO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a certified reference material (CRM), 8-fluoro-2,3,4,5-tetrahydro-1,4-benzoxazepine 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.
