Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 206.47 g/mol gives 3-Bromo-4-chloroaniline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-Bromo-4-chloroaniline (CAS 823-54-1), molecular formula C6H5BrClN and molecular weight 206.47 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, chlorine/bromine substitution, an aromatic ring system, 3-Bromo-4-chloroaniline is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 206.47 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 3-Bromo-4-chloroaniline 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.
