Chemical Structure
Description
The occurrence of 3-Fluoro-2-methylaniline hydrochloride is closely related to a nitrile group, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-Fluoro-2-methylaniline hydrochloride (CAS 654-20-6) is a high-purity analytical reference standard with the molecular formula C7H8FNHCl and a molecular weight of 161.60 g/mol.
3-Fluoro-2-methylaniline hydrochloride (C7H8FNHCl) contains a nitrile group, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
As a certified reference material (CRM), 3-Fluoro-2-methylaniline 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.
