Chemical Structure
Description
(S)-1-(3,4-Dimethylphenyl)propan-1-amine hydrochloride (CAS 1777812-71-1), molecular formula C11H17NHCl and molecular weight 199.72 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (S)-1-(3,4-Dimethylphenyl)propan-1-amine hydrochloride (C11H17NHCl) contains a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 199.72 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
