Chemical Properties
Didecanoyl peroxide is commercially available as white
flakes, with a musty odor, insoluble in water, but soluble
in organic solvents. It is used as polymerization initiator. The
deflagration hazard was measured for this organic peroxide
. The didecanoyl peroxide in powder form showed no
pressure rise using 5 g of igniter at 98% purity when using the
revised time–pressure test. This measurement determined
that didecanoyl peroxide is not a deflagration hazard.
General Description
White wet solid. May float or sink in water. bisdecanoyl peroxide is particularly sensitive to temperature rises, contamination, and friction. Above a given "Control Temperature" they decompose violently.
Reactivity Profile
Peroxides, such as bisdecanoyl peroxide, are good oxidizing agents. Organic compounds can ignite on contact with concentrated peroxides. Strongly reduced material such as sulfides, nitrides, and hydrides may react explosively with peroxides. There are few chemical classes that do not at least produce heat when mixed with peroxides. Many produce explosions or generate gases (toxic and nontoxic). Generally, dilute solutions of peroxides (<70%) are safe, but the presence of a catalyst (often a transition metal such as cobalt, iron, manganese, nickel, or vanadium) as an impurity may even then cause rapid decomposition, a buildup of heat, and even an explosion. Solutions of peroxides often become explosive when evaporated to dryness or near-dryness. Danger of explosion when dry. May explode from heat, shock, friction or contamination. May ignite combustibles (wood, paper, oil, clothing, etc.). May be ignited by heat, sparks or flames.
Check Digit Verification of cas no
The CAS Registry Mumber 762-12-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,6 and 2 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 762-12:
(5*7)+(4*6)+(3*2)+(2*1)+(1*2)=69
69 % 10 = 9
So 762-12-9 is a valid CAS Registry Number.

Bu4NI-Catalyzed, Radical-Induced Regioselective N-Alkylations and Arylations of Tetrazoles Using Organic Peroxides/Peresters

Bu4NI-catalyzed regioselective N2-methylation, N2-Alkylation, and N2-Arylation of tetrazoles have been achieved using tert-butyl hydroperoxide (TBHP) as the methyl source, alkyl diacyl peroxides as the primary alkyl source, alkyl peresters as the secondary and tertiary alkyl sources, and aryl diacyl peroxides as the arylating source. These reactions proceed without pre-functionalization of tetrazole and in the absence of any metal catalysts. Here, peroxides serve the dual role of oxidants as well as alkylating or arylating agents. Based on DFT calculations, it was found that spin density, transition-state barriers (kinetic control), and thermodynamic stability of the products (thermodynamic control) play essential roles in the observed regioselectivity during N-Alkylation. This radical-mediated process is amenable to a broad range of substrates and provides products in moderate to good yields.
