644-31-5 Usage
Chemical Properties
Acetyl benzoyl peroxide is a white crystalline solid, forming needles.
Uses
Germicide; in bleaching of flour and food oils.
General Description
A solution containing less than 40% by mass of the white crystalline solid in a nonvolatile solvent. Dilution moderates reactivity of the pure solvent. Irritating to the skin, eyes and mucous membranes.
Air & Water Reactions
Decomposed by water [Hawley].
Reactivity Profile
Acetyl benzoyl peroxide SOLUTION [<= 40% PEROXIDE] is a powerful oxidizing agent. Reacts with reducing agents (including many common organic materials). These reactions may lead to ignition. Decomposes when heated.
Safety Profile
Poison by inhalation and ingestion. Severe irritant. A powerful oxidzing agent that is corrosive to the skin and mucous membranes. See also PEROXIDES, ORGANIC. Dangerous; shock or heat will cause detonation with evolution of toxic fumes; will react with water or steam to produce heat; can react vigorously with reducing materials. Flammable by spontaneous chemical reaction. To fight fire, use Con or dry chemical. When heated to decomposition it emits acrid smoke and fumes.
Potential Exposure
Used in disinfectants, to bleach flour; and in medications.

Check Digit Verification of cas no
The CAS Registry Mumber 644-31-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,4 and 4 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 644-31:
(5*6)+(4*4)+(3*4)+(2*3)+(1*1)=65
65 % 10 = 5
So 644-31-5 is a valid CAS Registry Number.

With the aid of an azo directing group, Pd-catalyzed ortho-sp2 C-H bond activation/functionalization of azoarenes with aryl acyl peroxides has been explored. This transformation provides easy access to regioselectively introducing acyloxyl and aryl groups into azoarenes by simply changing the reaction temperature and solvent. This journal is the Partner Organisations 2014.
