Chemical Structure
Description
The occurrence of N-(2-Bromophenyl)nitrosamide is closely related to an amide group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
N-(2-Bromophenyl)nitrosamide (CAS 876497-67-5) is a high-purity analytical reference standard with the molecular formula C6H5BrN2O and a molecular weight of 201.02 g/mol.
N-(2-Bromophenyl)nitrosamide (C6H5BrN2O) contains an amide group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
