Chemical Structure
Description
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.
CATO supplies 3,3-Dimethyl-1-(5-methylthiophen-2-yl)butan-1-amine (CAS 1020948-05-3), a certified reference material (molecular formula C11H19NS, MW 197.34 g/mol) for analytical method development and quality control.
Structurally, 3,3-Dimethyl-1-(5-methylthiophen-2-yl)butan-1-amine (C11H19NS) contains a nitrile group, sulfur-containing functionality. 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 197.34 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
