4-Fluoroaniline Hydrochloride CAS 2146-07-8 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

4-Fluoroaniline Hydrochloride (CAS 2146-07-8), molecular formula C6H6FNHCl and molecular weight 147.58 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-Fluoroaniline Hydrochloride (C6H6FNHCl) is characterized by a nitrile group, fluorine/chlorine substitution. 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.

As a certified reference material (CRM), 4-Fluoroaniline Hydrochloride 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.
