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 N-[1-(5-bromo-2,3-dihydro-1-benzofuran-3-yl)ethylidene]hydroxylamine.
N-[1-(5-bromo-2,3-dihydro-1-benzofuran-3-yl)ethylidene]hydroxylamine (CAS 1807938-36-8) is a high-purity analytical reference standard with the molecular formula C10H10BrNO2 and a molecular weight of 256.10 g/mol.
N-[1-(5-bromo-2,3-dihydro-1-benzofuran-3-yl)ethylidene]hydroxylamine (C10H10BrNO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), N-[1-(5-bromo-2,3-dihydro-1-benzofuran-3-yl)ethylidene]hydroxylamine 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.
