1680-51-9 Usage

General Description

6-Methyltetraline is a chemical compound that belongs to the class of hydrocarbons and is also known as 1-methyl-4-isopropylnaphthalene. It is a colorless liquid with a strong aromatic odor and is insoluble in water. 6-Methyltetraline is commonly used as a solvent and in the production of other chemicals, and it has also been studied for its potential pharmaceutical and medicinal applications. Additionally, it is important to handle this chemical with care as it may be harmful if swallowed or inhaled, and can cause skin and eye irritation.

Check Digit Verification of cas no

The CAS Registry Mumber 1680-51-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,8 and 0 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1680-51:
(6*1)+(5*6)+(4*8)+(3*0)+(2*5)+(1*1)=79
79 % 10 = 9
So 1680-51-9 is a valid CAS Registry Number.

Biomimetic Radical Ring Expansion and Aromatisation; a Model for the Biogenesis of Natural Ring-D Aromatic Steroids

Green, Stuart P.,Whiting, Donald A.

, p. 1754 - 1755 (1992)

Photolysis of the thiohydroxamate 7 generated the carbon radical 9, which rearranged and aromatised to the methyltetralin 8, providing a model for the biogenesis of the insect antifeedant steroid nic-11 from the conventional C/D precursor nic-3 2: photolysis of the isomeric thiohydroxamate 13 gave both methyltetralins 8 and 14, through an unusual rearrangement sequence, possibly involving the benzvalene related radical 17.

Effect of Composition of Cobalt-Molybdenum-Containing Sulfonium Thiosalts on the Hydrogenation Activity of Nanosized Catalysts In Situ Synthesized on Their Basis

Knyazeva,Panyukova,Kuchinskaya,Kulikov,Maximov

, p. 1285 - 1292 (2019)

Abstract: Cobalt-molybdenum-containing thiosalts with different composition of the sulfonium cation are prepared. The activities of sulfide catalysts in situ synthesized on their basis in the hydrogenation of substituted naphthalenes are compared. It is shown that the sulfonium cation composition affects the morphology of the sulfide particles and the phase composition of the catalyst. It is demonstrated that the conversion of model alkyl-substituted bicyclic aromatic hydrocarbons is higher in the presence of the catalyst prepared from the phenylsulfonium thiosalt.

A new precursor for synthesis of nickel-tungsten sulfide aromatic hydrogenation catalyst

Serdyukov,Kniazeva,Sizova,Zubavichus,Dorovatovskii,Maximov

, (2021)

The unsupported NiWS-catalyst was obtained from the precursor [Ph3S]2Ni(WS4)2 in a hydrocarbon medium (in situ) for hydrogenation bicyclic aromatic compounds. The precursor [Ph3S]2Ni(WS4)2 and the catalyst prepared on its basis were studied by the X-ray diffraction and X-ray absorption methods, XPS and TEM. It was found that the new catalyst formed in situ contains tungsten sulfide and nickel sulfide nanophases. Tungsten sulfide, which has a layered structure, partially forms an insertion compound with nickel that enters between the WS2 layers and bonds covalently to sulfur. The proposed catalyst has proved to be active in the hydrodearomatization processes of model aromatic compounds (naphthalene, methylnaphthalenes) and exhibited the maximum selectivity with the formation of decalins compared to other earlier studied catalysts formed from other precursors in the reaction medium.
