40327-01-3 Usage
General Description
2,3-dibromo-3-phenylpropyl benzoate is a chemical compound with the molecular formula C16H13Br2O2. Also known as dibromphenylpropylbenzoate, it is a white to off-white crystalline powder that is sparingly soluble in water but soluble in organic solvents. It is commonly used as a UV absorber and photostabilizer in various products such as plastics, coatings, and cosmetics to prevent degradation caused by exposure to sunlight. Additionally, it is also used as an intermediate in the synthesis of pharmaceuticals and other organic compounds. Due to its potential for skin and eye irritation, as well as its environmental persistence, proper handling and disposal practices are necessary when working with this chemical.
Check Digit Verification of cas no
The CAS Registry Mumber 40327-01-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,3,2 and 7 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 40327-01:
(7*4)+(6*0)+(5*3)+(4*2)+(3*7)+(2*0)+(1*1)=73
73 % 10 = 3
So 40327-01-3 is a valid CAS Registry Number.

Dibromination of alkenes with LiBr and H2O2 under mild conditions
Martins, Nayara Silva,Alberto, Eduardo E.
supporting information, p. 161 - 167 (2017/12/28)
Electron-rich and electron-poor alkenes, and alkenes bearing protecting groups can be efficiently and stereoselectively converted to trans-dibromides using LiBr/H2O2 and AcOH as a proton source in 1,4-dioxane. For most substrates addition of 0.1 mol% of PhTeTePh enhances the reaction rate and the yield of the products. Experimental data suggest that the brominating agent prepared in situ is molecular bromine and that LiBr assists the activation of H2O2 allowing bromination to occur using AcOH as a mild proton source in uncatalyzed experiments. Scale-up is feasible: 10.0 mmol of 1-octene was quantitatively converted to 1,2-dibromooctene in one hour of reaction at room temperature.
