Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 185.69 g/mol gives (S)-1-(3,4-Dimethylphenyl)ethanamine hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(S)-1-(3,4-Dimethylphenyl)ethanamine hydrochloride (CAS 1212186-90-7), molecular formula C10H15NHCl and molecular weight 185.69 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, chlorine substitution, (S)-1-(3,4-Dimethylphenyl)ethanamine hydrochloride is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 185.69 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
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.
