Uses
Used in Pesticide Industry:
L-Alanine, N-(2-ethyl-6-methylphenyl)is used as a key intermediate in the chemoenzymic synthesis of the chiral herbicide (S)-metolachlor. This herbicide is effective in controlling a wide range of weeds and is a more environmentally friendly alternative to traditional herbicides due to its chiral nature, which allows for targeted weed control with reduced impact on non-target organisms.
As a Pesticide Metabolite:
L-Alanine, N-(2-ethyl-6-methylphenyl)also serves as a pesticide metabolite, which is an important aspect of understanding the environmental impact and degradation pathways of the herbicide (S)-metolachlor. Studying metabolites can help in assessing the safety and efficacy of the herbicide, as well as in developing strategies for its proper disposal and management.
Check Digit Verification of cas no
The CAS Registry Mumber 82508-03-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,5,0 and 8 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 82508-03:
(7*8)+(6*2)+(5*5)+(4*0)+(3*8)+(2*0)+(1*3)=120
120 % 10 = 0
So 82508-03-0 is a valid CAS Registry Number.

Chemoenzymatic synthesis of the chiral herbicide: (S)-metolachlor

A chemoenzymatic approach for the production of (5)-metolachlor, one of the most widely used herbicides, has been developed. The starting material (S)-N-(2-ethyl-6-methylphenyl)alanine was obtained by the use of lipase-catalyzed hydrolytic kinetic resolution. Under the optimal conditions, the good activity and excellent enantioselectivity of lipase B from Candida antarctica (CAL-B, E > 100) are achieved in diethyl ether - water (15% v/v), which is about 9.7-fold more enantioselective than that in a pure buffered aqueous solution (E = 12.1). After a simple extraction procedure is used to separate the acid product from the remaining ester, the remaining ester is racemized, providing the basis for the continuous resolution process. Then (S)-metolachlor is synthesized by a simple chemical method using the enantiomerically pure (S)-acid.
