Chemical Structure
Description
3-Bromo-4,5-dimethylbenzene-1,2-diamine (CAS 692717-83-2), molecular formula C8H11BrN2 and molecular weight 215.09 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C8H11BrN2, 3-Bromo-4,5-dimethylbenzene-1,2-diamine contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 215.09 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
