Chemical Structure
Description
The occurrence of (S)-1-(3-Chloro-4-methylphenyl)ethan-1-amine hydrochloride is closely related to a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies (S)-1-(3-Chloro-4-methylphenyl)ethan-1-amine hydrochloride (CAS 1269469-78-4), a certified reference material (molecular formula C9H12ClNHCl, MW 206.11 g/mol) for analytical method development and quality control.
(S)-1-(3-Chloro-4-methylphenyl)ethan-1-amine hydrochloride (C9H12ClNHCl) contains a nitrile group, 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.
