Description
CATO manufactures 4-Fluoroaniline Hydrobromide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
4-Fluoroaniline Hydrobromide (CAS 85734-18-5), molecular formula C6H6FNHBr and molecular weight 192.03 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, fluorine/bromine substitution, 4-Fluoroaniline Hydrobromide is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 192.03 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
