Description
2-CHLORO-N-(2-ETHYL-6-METHYLPHENYL)-N-[(1S)-2-METHOXY-1-METHYLETHYL]ACETAMIDE, also known as (R)-Metolachlor, is the R-enantiomer of Metolachlor (M338700(P)), an acyanilide herbicide similar to selective pre-emergence herbicides. It is characterized by its chemical structure and is considered a contaminant of emerging concern (CECs) by the United States Environmental Protection Agency (EPA).
Uses
Used in Agricultural Industry:
2-CHLORO-N-(2-ETHYL-6-METHYLPHENYL)-N-[(1S)-2-METHOXY-1-METHYLETHYL]ACETAMIDE is used as an acyanilide herbicide for controlling weeds in various crops. Its application reason is due to its selective pre-emergence properties, which help in managing weed growth without causing significant harm to the desired crops.
Used in Environmental Studies:
2-CHLORO-N-(2-ETHYL-6-METHYLPHENYL)-N-[(1S)-2-METHOXY-1-METHYLETHYL]ACETAMIDE is used as a contaminant of emerging concern (CECs) in environmental studies. Its application reason is to assess the potential impact of this herbicide on groundwater quality and to develop strategies for mitigating its presence in the environment.
Used in Regulatory Frameworks:
2-CHLORO-N-(2-ETHYL-6-METHYLPHENYL)-N-[(1S)-2-METHOXY-1-METHYLETHYL]ACETAMIDE is used as a Drinking Water Contaminant Candidate List 3 (CCL 3) compound by the United States Environmental Protection Agency (EPA). Its application reason is to evaluate the potential risks associated with its presence in drinking water and to establish guidelines for safe exposure levels.
Check Digit Verification of cas no
The CAS Registry Mumber 178961-20-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,8,9,6 and 1 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 178961-20:
(8*1)+(7*7)+(6*8)+(5*9)+(4*6)+(3*1)+(2*2)+(1*0)=181
181 % 10 = 1
So 178961-20-1 is a valid CAS Registry Number.

PROCESS FOR PREPARING AMINES AND A CARBOXAMIDE THEREOF
-
Page/Page column 23, (2010/02/15)
Chiral, secondary amines of the formula (I) or (II), where R01, R02 and R03 are each, independently of one another, C1-C4-alkyl, R04 is C1-C4-alkyl, C1-C4-alkoxymethyl or C1-C4-alkoxyethyl, and * indicates predominantly one configurational isomer, can be obtained by hydrogenation of corresponding ketimines in the presence of iridium complexes with chiral ferrocene tetraphosphines in which a secondary phosphine group and 1-secondary phosphinalk-1-yl are bound to each cyclopentadienyl ring in ortho positions.
ENANTIOSELECTIVE SYNTHESIS OF OPTICALLY ACTIVE METOLACHLOR VIA ASYMMETRIC REDUCTION
Cho, Byung Tae,Chun, Yu Sung
, p. 337 - 340 (2007/10/02)
Optically active metolachlor was prepared by chloroacetylation of the corresponding amine obtained by asymmetric reduction of the requisite imine with the chiral hydrides, such as Itsuno's reagent (4), Corey's reagent (5) and K glucoride (6).
