5-(2-Pyridinyl)-2-thiophenecarboxaldehyde CAS 132706-12-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 189.23 g/mol gives 5-(2-Pyridinyl)-2-thiophenecarboxaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 5-(2-Pyridinyl)-2-thiophenecarboxaldehyde (CAS 132706-12-8), a certified reference material (molecular formula C10H7NOS, MW 189.23 g/mol) for analytical method development and quality control.

Structurally, 5-(2-Pyridinyl)-2-thiophenecarboxaldehyde (C10H7NOS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 189.23 g/mol, it falls into the medium-molecular-weight range. 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.
