3-Ethyl-4-propylthiophene CAS 147871-87-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Ethyl-4-propylthiophene.

3-Ethyl-4-propylthiophene (CAS 147871-87-2) is a high-purity analytical reference standard with the molecular formula C9H14S and a molecular weight of 154.27 g/mol.

The molecular framework of 3-Ethyl-4-propylthiophene (C9H14S) is characterized by sulfur-containing functionality. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional 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.
