Chemical Structure
Description
Based on its molecular formula C11H17NS, (5,5-dimethyl-4,5,6,7-tetrahydro-1-benzothiophen-2-yl)methanamine contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 195.32 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
(5,5-dimethyl-4,5,6,7-tetrahydro-1-benzothiophen-2-yl)methanamine (CAS 1376224-89-3) is a high-purity analytical reference standard with the molecular formula C11H17NS and a molecular weight of 195.32 g/mol.
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.
