Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 4,5,6,7-Tetrahydro-2H-isoindole is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 121.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
CATO supplies 4,5,6,7-Tetrahydro-2H-isoindole (CAS 51649-35-5), a certified reference material (molecular formula C8H11N, MW 121.18 g/mol) for analytical method development and quality control.
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.
