Chemical Structure

2,3,4,9-tetrahydrocarbazol-1-one CAS 3456-99-3 chemical structure

Description

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 2,3,4,9-tetrahydrocarbazol-1-one is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 193.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

2,3,4,9-tetrahydrocarbazol-1-one (CAS 3456-99-3), molecular formula C12H19NO and molecular weight 193.29 g/mol, is a CATO reference standard with documented purity and traceability.

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.
