1107-26-2 Usage
Content analysis
Sample solution A: Accurately weigh about 40 mg of the sample, transfer it into a 100 ml volumetric flask, dissolve it in 10 ml of acid-free chloroform, make up to volume with cyclohexane and mix well. Pipette 2ml of this solution into a 50ml volumetric flask, dilute to volume with cyclohexane and mix well. Pipette 5ml of sample solution A into a 50ml volumetric flask with sample solution B, dilute to volume with cyclohexane and mix well. Determination step Use a suitable spectrophotometer to measure the absorbance of sample solution B in a 1CiTI absorption cell at the maximum absorption wavelength of about 460nm, and use cyclohexane as a blank test solution. Calculate the content (in mg) of this product (C30H40O) in the sample according to the formula 25000A/264, where A is the absorbance of the solution, and 264 is the absorbance coefficient of pure β-apocarcinaldehyde.

lic sheen or violet crystals.Sol in chlo-
roform; sltly sol in acetone; insol in water.
Uses
Different sources of media describe the Uses of 1107-26-2 differently. You can refer to the following data:
1. β-apo-8 -carotenal is used to color juices, fruit drinks, soups, jams, jellies, and gelatin.
2. β-Apo-8'-carotenal is an antioxidant β-carotene (C184250) derivative found in Cucumis melo melons and traditional Portuguese fruits and vegetables. Studies have shown that β-Apo-8'-carotenal decreased
the in vivo AFB1-induced DNA SSB and the binding of AFB1 to liver DNA and increased in vitro AFB1 metabolism to aflatoxin M1, a less genotoxic metabolite.
3. Beta-Apo-8'-Carotenal is a colorant that is a carotenoid producing a light to dark orange hue. It has fair light stability, poor oxidation stability, and good ph stability. It is insoluble in water but is available in water-dispersible, oil-dispersible, and oil-soluble forms. It has vitamin a activity. It is used in cheese and cheese sauces, and dressings. The maximum usage level is 33 ppm. Related colorants are beta-carotene and canthaxanthin.
Definition
ChEBI: An apo carotenoid triterpenoid compound arising from oxidative degradation of the beta,beta-carotene skeleton at the 8'-position.
General Description

Check Digit Verification of cas no
The CAS Registry Mumber 1107-26-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,0 and 7 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1107-26:
(6*1)+(5*1)+(4*0)+(3*7)+(2*2)+(1*6)=42
42 % 10 = 2
So 1107-26-2 is a valid CAS Registry Number.

Efficient oxidation of β?carotene in μ-carbido diiron octapropyltetraazaporphyrin–tBuOOH system
, ()
The oxidative decomposition of β?carotene mediated by μ-carbido diiron octapropyltetraazaporphyrin ([FeOPrTAP]2C)–tBuOOH system was investigated in benzene. Interaction between tBuOOH and the binuclear complex resulted in the generation of powerful high-oxidized species those are capable of oxidizing the employed substrate within the limits of several minutes. The explanation for such reactivity behavior involves the existence of a mixture of reactive intermediates in the reaction medium: more stable singly oxidized at the macrocyclic ligand π-cation radical as well as much more reactive dication species that is more contributing to the reaction rate. The introduction of imidazole into the coordination sphere of the initial diiron complex accelerates the β?carotene destruction because of generation of a powerful high-oxidizing species, which is capable of oxidizing β?carotene as well as the applied organic peroxide resulting in dioxygen release. Catalytic behavior of all the observed active intermediates was supported by recycling of the reaction under carotene adding. The quantitative characteristics of reactivity of studied systems were obtained and the possible reaction mechanisms were proposed.

Mild oxidative cleavage of β,β-carotene by dioxygen is induced by a ruthenium tetramesitylporphyrin catalyst, and it leads to the full possible range of β-apocarotenals and β-apocarotenones. The slow reaction kinetics allow the sequence of events leading to double bond cleavage over a period of 24 h to be monitored by HPLC-DAD and HPLC-MS.
