Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Bromo-2-chloro-6-iodoaniline, 97%.
4-Bromo-2-chloro-6-iodoaniline, 97% (CAS 56141-11-8), molecular formula C6H4BrClIN and molecular weight 332.36 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Bromo-2-chloro-6-iodoaniline, 97% (C6H4BrClIN) is characterized by a nitrile group, chlorine/bromine/iodine 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.
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.
