3,4,5,11-Tetrahydroacenaphthene CAS 26761-12-6 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

3,4,5,11-Tetrahydroacenaphthene (CAS 26761-12-6), molecular formula C12H12 and molecular weight 156.22 g/mol, is a CATO reference standard with documented purity and traceability.

3,4,5,11-Tetrahydroacenaphthene (C12H12) contains an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
