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-N1-methyl-1,2-benzenediamine (CAS 69038-76-2), molecular formula C7H9BrN2 and molecular weight 201.06 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Bromo-N1-methyl-1,2-benzenediamine (C7H9BrN2) is characterized by a nitrile group, bromine substitution, an aromatic ring system. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a certified reference material (CRM), 4-Bromo-N1-methyl-1,2-benzenediamine 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.
