Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 280.50 g/mol gives 1-Bromo-2-chloro-5-ethoxy-4-nitrobenzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1-Bromo-2-chloro-5-ethoxy-4-nitrobenzene (CAS 1393442-06-2), a certified reference material (molecular formula C8H7BrClNO3, MW 280.50 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, 1-Bromo-2-chloro-5-ethoxy-4-nitrobenzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 280.50 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
