Chemical Structure
Description
(S)-1-(2-Fluoro-4-methylphenyl)ethan-1-amine hydrochloride (CAS 1929520-91-1) is a high-purity analytical reference standard with the molecular formula C9H12FNHCl and a molecular weight of 189.66 g/mol.
(S)-1-(2-Fluoro-4-methylphenyl)ethan-1-amine hydrochloride (C9H12FNHCl) 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.
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.
