It is known that enantioselectivity of enzymes depends on many different parameters such as temperature, substrate structure, reaction medium, and presence of water. Enantiopreference of enzymes can be greatly affected, even reversed, by changing the reaction solvent. Such an example was reported by Ueji et al. in 1992 for Candida cylindracea lipase-catalyzed esterification of ( )-2-phenoxy propionic acid with 1-butanol [29]. 

In Jamaica,302 no effect was found from (2,4-dichlorophenoxy)acetic acid, but positive responses were obtained from low rates of application (less than 0.009 lb. per acre) of (2,4,5-trichlorophenoxy)acetic acid and 2-(2,4,5 trichlorophenoxy)propionic acid. Louisiana sugarcane failed to respond to the low rates of (2,4-dichloro- or (2,4,5-trichloro-phenoxy)-acetic acid, but (2,4-dichlorophenoxy)acetic acid at one and three lb. per acre increased the sugar yield significantly at eight days, although not at 25 or 39 days.31 ... 

Many other compounds have been included in studies on sucrose response. Most of these have been herbicides or enzyme poisons. None of the common herbicides had any positive effect on sucrose at rates up to that causing severe foliar injury. Earlier reports of response from 2-(2,4,5-trichlorophenoxy)propionic acid and 2,2-dichloropropionic acid could not be substantiated in British Guiana and Queensland. 27 Some compounds, such as 3-(p-chlorophenyl)-l,l-dimethylurea (monuron), (2,4-dichloro-phenoxy) acetic acid in soil, ethylenediaminetetraacetic acid, and leaf desiccants decreased sucrose and juice solids content. 20 Field trials with several chemicals in Trinidad showed enhanced sucrose at 14 to 28 days before harvest resulting from the application of 8 and 12 lb. (per acre) of... 

BASF (Ludwigshafen, Germany) produces isomerically pure (i )-2-(4-hydroxy-phenoxy)-propionic acid (HPOPS) from (P)-2-phenoxypropionic add (POPS) on a 100 m3 fermenter scale for use as a herbicide intermediate (Figure 7.30) (Cooper, 1990). 

Cleavage of the ether linkage of the 2,4-dichlorophenoxyalkanoic acids by a strain of Flavobacterium to yield the intact alkanoic acid and 2,4-dichlorophenol has also been observed (34,35). The intact alkanoic acid is further metabolized by beta oxidation. The bacterium produced the free fatty acid corresponding to the aliphatic moieties of six omega-linked dichlorophenoxyalkanoic acids in the series from 3-(2,4-dichloro-phenoxy) propionic acid to 8-(2,4-dichlorophenoxy)octanoic acid.

Disposition in the Body. Well absorbed after oral administration bioavailability about 50% due to extensive first-pass metabolism. About 95% of a dose is excreted in the urine within 48 hours, with about 65% of the dose as the inactive metabolite, 4-(2-hydroxy-3-isopropylaminopropoxy)phenylacetic acid, and about 10% as a further inactive metabolite, 2-hydroxy-3-[4-(2-meth-oxyethyl)phenoxy]propionic acid. Two active metabolites, a-hydroxymetoprolol and O-desmethylmetoprolol are also excreted in the urine in amounts equivalent to about 10% and less than 1% of the dose, respectively. Up to about 10% of a dose is excreted as unchanged drug.

P-chloro-o-cresol is the precursor for the pesticides MCPA (2-methyl-4-chloro-phenoxyacetic acid), MCPP (2-methyl-4-chloro-phenoxy propionic acid) and MCPB (2-methyl-4-chloro-phenoxy butyric acid). MCPP is also known as mecoprop.
