Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 197.25 g/mol gives 1-(Thiophen-2-ylmethyl)azetidine-2-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1-(Thiophen-2-ylmethyl)azetidine-2-carboxylic acid (CAS 1042440-43-6), a certified reference material (molecular formula C9H11NO2S, MW 197.25 g/mol) for analytical method development and quality control.
Based on its molecular formula C9H11NO2S, 1-(Thiophen-2-ylmethyl)azetidine-2-carboxylic acid contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 197.25 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
