Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 352.57 g/mol gives tert-Butyl (5-bromo-6-chloro-3-nitropyridin-2-yl)carbamate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
tert-Butyl (5-bromo-6-chloro-3-nitropyridin-2-yl)carbamate (CAS 2680741-05-1) is a high-purity analytical reference standard with the molecular formula C10H11BrClN3O4 and a molecular weight of 352.57 g/mol.
The molecular framework of tert-Butyl (5-bromo-6-chloro-3-nitropyridin-2-yl)carbamate (C10H11BrClN3O4) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
