5-formylthiophene-3-carbonitrile CAS 51770-04-8

Description

The occurrence of 5-formylthiophene-3-carbonitrile is closely related to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-formylthiophene-3-carbonitrile (CAS 51770-04-8) is a high-purity analytical reference standard with the molecular formula C6H7NOS and a molecular weight of 141.19 g/mol.

Based on its molecular formula C6H7NOS, 5-formylthiophene-3-carbonitrile contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 141.19 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
