119-13-1 Usage
Chemical Properties
clear yellow to brownish viscous liquid
Uses
Different sources of media describe the Uses of 119-13-1 differently. You can refer to the following data:
1. One of the naturally occurring forms of Vitamin E. Isolated from soybean oil.
2. (+)-δ-Tocopherol has been used as a reference material for its extraction from oil using high performance liquid chromatography (HPLC). It has also been used as a standard to quantify δ-tocopherol in soybean using reverse-phase high performance liquid chromatography.
General Description
δ-Tocopherol, a homolog of vitamin E, is a phytochemical with potent antioxidant activity. It has been investigated for its potential medical, biological, and physio-chemical applications.
Biochem/physiol Actions
Tocopherols (TCP) (vitamin E) are a series (α, β, γ and δ) of chiral organic molecules that vary in their degree of methylation of the phenol moiety of the chromanol ring. Tocopherols are fat soluble anti-oxidants that protect cell membranes from oxidative damage. δ-T is methylated at the 8-position. It has an anticancer property. δ-T is involved in proinflammatory response initiated by reactive oxygen species. It lowers lipid accumulation and promotes neuronal differentiation. δ-T also has antiangiogenic and natriuretic activities.
Check Digit Verification of cas no
The CAS Registry Mumber 119-13-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,1 and 9 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 119-13:
(5*1)+(4*1)+(3*9)+(2*1)+(1*3)=41
41 % 10 = 1
So 119-13-1 is a valid CAS Registry Number.

Page/Page column 9; 10, (2014/10/15)
The present invention provides a method for converting an aromatic hydrocarbon to a phenol by providing an aromatic hydrocarbon comprising one or more aromatic C-H bonds and one or more activated C-H bonds in a solvent; adding a phthaloyl peroxide to the solvent; converting the phthaloyl peroxide to a di-radical; contacting the di-radical with the one or more aromatic C-H bonds; oxidizing selectively one of the one or more aromatic C-H bonds in preference to the one or more activated C-H bonds; adding a hydroxyl group to the one of the one or more aromatic C-H bonds to form one or more phenols; and purifying the one or more phenols.

The substrate specificity of the enzyme tocopherol cyclase from the blue-green algae Anabaena variabilis (Cyanobacteria) was investigated with 11 substrate analogues revealing the significance of three major recognition sites: (i) the OH group at C(1) of the hydroquinone, (ii) the (E) configuration of the double bond, and (iii) the length of the lipophilic side chain. Experiments with two affinity matrices suggest that substrates approach the enzyme's active site with the hydrophobic tail.
