Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 218.00 g/mol gives 2-Bromo-3-nitrophenol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2-Bromo-3-nitrophenol (CAS 101935-40-4), a certified reference material (molecular formula C6H4BrNO3, MW 218.00 g/mol) for analytical method development and quality control.
Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, 2-Bromo-3-nitrophenol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 218.00 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-Bromo-3-nitrophenol 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.
