Description

The occurrence of 1742-14-9 K2ND496F5P 1,1-Bis(3,4-dimethylphenyl)ethane Benzene, 1,1'-ethylidenebis(3,4-dimethyl- alpha-(3,4-Dimethylphenyl)-alpha-methyl-3,4-dimethyltoluene 1,1-Di-3,4-xylylethane EINECS 217-108-0 UNII-K2ND496F5P Ethane, 1,1-di-3,4-xylyl- is closely related to a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1742-14-9 K2ND496F5P 1,1-Bis(3,4-dimethylphenyl)ethane Benzene, 1,1'-ethylidenebis(3,4-dimethyl- alpha-(3,4-Dimethylphenyl)-alpha-methyl-3,4-dimethyltoluene 1,1-Di-3,4-xylylethane EINECS 217-108-0 UNII-K2ND496F5P Ethane, 1,1-di-3,4-xylyl- (CAS 1742-14-9), molecular formula C18H22 and molecular weight 238.37 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a polycyclic aromatic system, 1742-14-9 K2ND496F5P 1,1-Bis(3,4-dimethylphenyl)ethane Benzene, 1,1'-ethylidenebis(3,4-dimethyl- alpha-(3,4-Dimethylphenyl)-alpha-methyl-3,4-dimethyltoluene 1,1-Di-3,4-xylylethane EINECS 217-108-0 UNII-K2ND496F5P Ethane, 1,1-di-3,4-xylyl- is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 238.37 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.

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.
