5-Cyanothiophene-2-carboxylic Acid CAS 59786-39-9

Description

Compared with other compounds in its class, the molecular weight of 153.16 g/mol gives 5-Cyanothiophene-2-carboxylic Acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-Cyanothiophene-2-carboxylic Acid (CAS 59786-39-9), molecular formula C6H3NO2S and molecular weight 153.16 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C6H3NO2S, 5-Cyanothiophene-2-carboxylic Acid contains an amide group, a sulfone group, a carboxylic acid group, 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 153.16 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.
