Chemical Structure
Description
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.
4,5-Dimethylthiophen-2-amine (CAS 87635-33-4) is a high-purity analytical reference standard with the molecular formula C6H9NS and a molecular weight of 127.21 g/mol.
Owing to a nitrile group, sulfur-containing functionality, 4,5-Dimethylthiophen-2-amine is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 127.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
