Uses
Used in Flavor and Fragrance Industry:
1,1,6-Trimethyltetralin is used as an intermediate in the synthesis of 1,2-Dihydro-1,1,6-trimethyl-naphthalene, which is responsible for imparting a "kerosene note" or "petrol" aroma in aged Riesling wines. This unique aroma characteristic is highly valued in the production of certain types of wines, adding complexity and depth to their flavor profiles.
Used in Chemical Synthesis:
1,1,6-Trimethyltetralin is also utilized in the synthesis of other organic compounds, particularly those with aromatic properties. Its versatile molecular structure allows it to be a key component in the creation of various fragrances, flavorings, and other specialty chemicals. This makes it an important substance in the development of new products across multiple industries, including pharmaceuticals, cosmetics, and materials science.
Check Digit Verification of cas no
The CAS Registry Mumber 475-03-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,7 and 5 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 475-03:
(5*4)+(4*7)+(3*5)+(2*0)+(1*3)=66
66 % 10 = 6
So 475-03-6 is a valid CAS Registry Number.

Ultrasound-Mediated Rearrangement of β-Ionone to 1,1,6-Trimethyl-1,2,3,4-Tetrahydronaphthalene.
Eshuis, Johan J. W.
, p. 7833 - 7836 (1994)
The rearrangement of β-ionone in CHBr3 to 1,1,6-trimethyl-1,2,3,4-tetrahydronaphthalene was studied under sonochemical conditions.Trapping experiments showed ultrasound to induce the generation of bromine radicals from CHBr3 that abstracted hydrogen from the solvent to yield HBr.The hydrogen bromide catalyses the cyclisation of β-ionone.

Synthesis and Herbicidal Activity of Substituted Tetrahydronaphthalenes: I
Parlow, John J.,Mahoney, Martin D.
, p. 137 - 144 (2007/10/03)
This paper reports the synthesis and the biological activity of substituted 6-alkyl-1,2,3,4-tetrahydro-1,1-dimethylnaphthalenes in which the substituents at the 5- and/or 7-position are varied with a multitude of functional groups. These compounds exhibited pre-emergent herbicidal activity which was a function of the electron-withdrawing ability and the size of the groups substituted at the 5- and/or 7-position. Nitro and/or nitrile groups at these positions tended to optimize activity.
