Chemical Structure
Description
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.
4,7-Methano-1H-indene, 3a,4,7,7a-tetrahydro-, polymer with ethenylbenzene, ethenylmethylbenzene, 1H-indene and (1-methylethenyl)benzene, hydrogenated (CAS 68442-05-7), molecular formula C10H12C9H10C9H8C8H8 and molecular weight 470.70 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4,7-Methano-1H-indene, 3a,4,7,7a-tetrahydro-, polymer with ethenylbenzene, ethenylmethylbenzene, 1H-indene and (1-methylethenyl)benzene, hydrogenated (C10H12C9H10C9H8C8H8) contains a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 18.0, corresponding to approximately 18 ring(s) or double-bond equivalent(s). With a molecular weight of 470.70 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
