Chemical Structure
Description
The occurrence of 1,1-Dimethyl-1,2,3,4-tetrahydronaphthalene is closely related to an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1,1-Dimethyl-1,2,3,4-tetrahydronaphthalene (CAS 1985-59-7) is a high-purity analytical reference standard with the molecular formula C12H16 and a molecular weight of 160.26 g/mol.
1,1-Dimethyl-1,2,3,4-tetrahydronaphthalene (C12H16) 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 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.
As a certified reference material (CRM), 1,1-Dimethyl-1,2,3,4-tetrahydronaphthalene meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
