54225-09-1 Usage
General Description
Propanoic acid, 2-chloro-, phenyl ester, also known as 2-chlorophenyl propionate or phenyl 2-chloropropanoate, is an organic compound with the chemical formula C9H9ClO2. It is a colorless liquid with a pleasant, fruity odor, and is commonly used as a flavoring agent and fragrance ingredient in the food and cosmetic industries. It is also used as a solvent for cellulose esters and ethers, and as an intermediate in the production of pharmaceuticals and agrochemicals. The compound is a mild skin and eye irritant, and should be handled with care to avoid contact with skin and eyes.
Check Digit Verification of cas no
The CAS Registry Mumber 54225-09-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,2,2 and 5 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 54225-09:
(7*5)+(6*4)+(5*2)+(4*2)+(3*5)+(2*0)+(1*9)=101
101 % 10 = 1
So 54225-09-1 is a valid CAS Registry Number.

Dichloromethane as a chlorination reagent for α-bromocarbonyl compounds in the presence of a copper catalyst
Takeuchi, Kentaro,Ishida, Syo,Nishikata, Takashi
supporting information, p. 644 - 646 (2017/08/30)
We found that dichloromethane is a powerful chlorinating reagent for the congested 3° and 2° Csp3Br bond of α-bromocarbonyl amides, esters, and ketones. In the presence of an appropriate copper complex as a catalyst, the desired chlorination occurred within an hour. Control experiments revealed that in situ-generated CuCl2 is a key chlorinating agent that reacts with the 3° or 2° alkyl radicals generated by the reaction between an α-bromocarbonyl compound and a Cu(I) salt.
