3-Methoxychroman-4-one, also known as vitamin E acetate, is a synthetic derivative of vitamin E (α-tocopherol). It is a colorless to pale yellow crystalline solid with a molecular formula of C16H18O3 and a molecular weight of 258.31 g/mol. 3-methoxychroman-4-one is characterized by a chroman-4-one ring structure, with a methoxy group at the 3-position and a hydroxyl group at the 5-position. 3-Methoxychroman-4-one is widely used in the pharmaceutical and cosmetic industries due to its antioxidant properties, which help protect cells from oxidative damage. It is also used as a stabilizer in various formulations to prevent the degradation of other ingredients. The compound is generally considered safe for use, but like any chemical, it should be handled with care to avoid potential adverse effects.

82366-82-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 82366-82-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,3,6 and 6 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 82366-82:
(7*8)+(6*2)+(5*3)+(4*6)+(3*6)+(2*8)+(1*2)=143
143 % 10 = 3
So 82366-82-3 is a valid CAS Registry Number.

Oxidation of 4-Chromanones with Thalium(III) Nitrate

Ciattini, Pier Giuseppe,Morera, Enrico,Ortar, Giorgio

, p. 395 - 400 (2007/10/02)

Treatment of 4-chromanones 1a-g with thalium(III) nitrate in acidic methanol results mainly in dehydrogenation, whereas α-methoxylation and/or Taylor-McKillop rearrangement predominante in trimethyl orthoformate.The mechanistic features of these oxidations are briefly discussed.
