(L177、L178)、Use Classification: Herbicides、Household Products: Information on 14 consumer products that contain 2-(2-Methyl-4-chlorophenoxy)propionic acid in the following categories is provided:、• Landscaping、Yard、• Pesticides、Information on 8 consumer products that contain Mecoprop-p in the following categories is provided:、Methods of Manufacturing: Mecoprop is produced by chlorination of 4-chloro-o-cresol and coupling with 2-chloropropionic acid. ... Mecoprop-P is produced analogously to Mecoprop from the corresponding propionic acid stereoisomer.、Formulations、Preparations: Turf Builder Plus 2 W、S for Grass (The Scotts Company): Active ingredient: MCPA 1.37%、mecoprop 1.37%.、The National Pesticide Information Retrieval System (NPIRS) identifies 13 companies with active labels for products containing the chemical mecoprop-p.

Subsequently、the dextro isomer was identified as the herbicidally active isomer、but no economic route was available to produce only the dextro isomer. In the 1980s、technologies were developed to produce the single enriched isomer form、MCPP-p、on a commercial scale、achieving approximately 93-95% purity of MCPP-p. ... In 1996、the technical manufacturers began to obtain EPA registrations for technical MCPP-p. Gradually、some end-use product (EUP) registrants began converting their formulations from the older racemic form to the single enriched isomer compositions. In September 2006、the Agency presented options to EUP registrants producing formulations that contained the racemic mecoprop: 1) convert their product formulations to contain the enriched isomer、2) produce data supporting the racemic mecoprop、or 3) submit voluntary cancelations for products they no longer wish to support. As of January 2007、EPA received voluntary cancelations or commitments to convert all product formulations to the enriched isomer、MCPP-p.、The WHO Recommended Classification of Pesticides by Hazard identifies mecoprop (technical grade) as Class III: slightly hazardous、Main Use: herbicide.、The WHO Recommended Classification of Pesticides by Hazard identifies mecoprop-p (technical grade) as Class II: moderately hazardous、Mecoprp-p。
