Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4-Bromo-5-methoxybenzene-1,2-diamine dihydrochloride (CAS 216752-62-4) is a high-purity analytical reference standard with the molecular formula C7H9BrN2OHCl and a molecular weight of 253.52 g/mol.
The molecular framework of 4-Bromo-5-methoxybenzene-1,2-diamine dihydrochloride (C7H9BrN2OHCl) is characterized by 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), 4-Bromo-5-methoxybenzene-1,2-diamine dihydrochloride 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.
