Chemical Structure
Description
1-(5-(2-Aminoethyl)thiophen-2-yl)ethan-1-ol (CAS 2839508-33-5), molecular formula C8H13NOS and molecular weight 171.26 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(5-(2-Aminoethyl)thiophen-2-yl)ethan-1-ol (C8H13NOS) is characterized by an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
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.
