Chemical Structure

2-Cyano-3-(5-methyl-2-thienyl)propionic Acid CAS 2044707-09-5 chemical structure

Description

2-Cyano-3-(5-methyl-2-thienyl)propionic Acid (C9H9NO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).

2-Cyano-3-(5-methyl-2-thienyl)propionic Acid (CAS 2044707-09-5) is a high-purity analytical reference standard with the molecular formula C9H9NO2S and a molecular weight of 195.24 g/mol.

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.

As a certified reference material (CRM), 2-Cyano-3-(5-methyl-2-thienyl)propionic Acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
