Cosmetic products
Extends shelf life, prevents rancidity
Mechanism of action
Neutralizes free radicals, prevents oxidative damage
Inhibition
Inhibits lipid peroxidation
Physical state
Likely a solid or viscous liquid (based on molecular weight and structure)
Solubility
Likely soluble in organic solvents (e.g., ethanol, acetone) due to its nonpolar nature

Synonyms
Other names include tert-butylhydroquinone acetate, TBHQ, and 2,5-Di-tert-butyl-4-acetoxyquinol
Chemical family
Phenolic antioxidants
Manufacturing
Synthesized from t-butylhydroquinone through acetylation
Stability
Stable under normal conditions, but sensitive to high temperatures, light, and moisture, which may affect its antioxidant activity
Check Digit Verification of cas no
The CAS Registry Mumber 22944-23-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,9,4 and 4 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 22944-23:
(7*2)+(6*2)+(5*9)+(4*4)+(3*4)+(2*2)+(1*3)=106
106 % 10 = 6
So 22944-23-6 is a valid CAS Registry Number.

Choice of Manganese(III) Complexes for the Synthesis of 4,4'-Biphenyldiols and 4,4'-Diphenoquinones
Nishino, Hiroshi,Nobuyuki, Itoh,Nagashima, Makiko,Kurosawa, Kazu
, p. 620 - 622 (2007/10/02)
2,6-Disubstituted phenols are oxidized with tris(2,4-pentanedionato)manganese(III), , in glacial acetic acid to give the corresponding 4,4'-biphenyldiols in high yields, whereas similar reactions using manganase(III) acetate, , instead of quantitatively yield the corresponding 4,4'-diphenoquinones.Cross-coupling reactions of 2,6-di-t-butylphenol and other substituted phenols afford the corresponding cross-coupled 4,4'-biphenyldiols and 4,4'-diphenoquinones together with oxidation products derived from them starting phenols themselves.The advantageous use of and Mn(OAc)3> in the ubiqitous phenol coupling reaction is discussed.
