Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 201.22 g/mol gives Methyl 2-cyano-2,3-dihydro-1H-indene-2-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Methyl 2-cyano-2,3-dihydro-1H-indene-2-carboxylate (CAS 260392-88-9), a certified reference material (molecular formula C12H11NO2, MW 201.22 g/mol) for analytical method development and quality control.
Structurally, Methyl 2-cyano-2,3-dihydro-1H-indene-2-carboxylate (C12H11NO2) contains an amino-acid-derived structure, an amide group, 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 201.22 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).
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.
