Chemical Structure
Description
(4-Bromo-3-chlorophenyl)hydrazine (CAS 103722-57-2), molecular formula C6H6BrClN2 and molecular weight 221.48 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C6H6BrClN2, (4-Bromo-3-chlorophenyl)hydrazine contains a nitrile group, chlorine/bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 221.48 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.
