Chemical Structure

2-<I>N</I>-Butylthiophene CAS 1455-20-5 chemical structure

Description

2-<I>N</I>-Butylthiophene (CAS 1455-20-5), molecular formula C8H16S and molecular weight 144.28 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C8H16S, 2-<I>N</I>-Butylthiophene contains sulfur-containing functionality; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 144.28 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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.
