3,4-Dihydroxy-α-methyl-L-phenylalanine ethyl ester, also known as L-DOPA ethyl ester, is a chemical compound derived from the amino acid L-DOPA (levodopa). It is characterized by the presence of two hydroxyl groups at the 3rd and 4th carbon positions, an α-methyl group, and an ethyl ester group. 3,4-Dihydroxy-α-methyl-L-phenylalanine ethyl ester is used as a precursor in the synthesis of various pharmaceuticals, particularly in the production of dopamine agonists, which are drugs that mimic the action of dopamine in the brain. L-DOPA ethyl ester is also utilized in research to study the effects of dopamine on neurological functions and to develop new treatments for conditions such as Parkinson's disease. Its chemical structure allows for better solubility and absorption compared to the parent compound, L-DOPA, making it a valuable intermediate in the pharmaceutical industry.

2544-09-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2544-09-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,4 and 4 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2544-09:
(6*2)+(5*5)+(4*4)+(3*4)+(2*0)+(1*9)=74
74 % 10 = 4
So 2544-09-4 is a valid CAS Registry Number.
