146387-12-4 Usage
General Description
Propanoic acid, 2-(2-fluorophenoxy)-, (2S)-, commonly known as fluofenpyr, is a chemical compound used as a herbicide to control a wide range of weeds in cereal crops, oilseed rape, and potatoes. It works by inhibiting the enzyme protoporphyrinogen oxidase, leading to the accumulation of toxic substances in the plants and ultimately causing their death. Fluofenpyr is a selective herbicide, meaning it targets specific types of weeds without harming the desired crop. It is typically applied as a foliar spray and has a relatively low toxicity to non-target organisms when used according to label directions. However, as with all herbicides, it is important to use fluofenpyr responsibly and follow proper safety precautions when handling and applying the chemical.
Check Digit Verification of cas no
The CAS Registry Mumber 146387-12-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,6,3,8 and 7 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 146387-12:
(8*1)+(7*4)+(6*6)+(5*3)+(4*8)+(3*7)+(2*1)+(1*2)=144
144 % 10 = 4
So 146387-12-4 is a valid CAS Registry Number.

A new method for production of chiral 2-aryloxypropanoic acids using effective kinetic resolution of racemic 2-aryloxycarboxylic acids

We report a novel method for the preparation of 2-aryloxypropanoic acids by kinetic resolution of racemic 2-aryloxypropanoic acids using enantioselective esterification. The usage of pivalic anhydride (Piv2O) as an activating agent, bis(a-naphthyl)methanol ((α-Np)2CHOH) as an achiral alcohol, and (+)-benzotetramisole ((+)-BTM) as a chiral acyl-transfer catalyst enables the effective separation of various racemic 2-aryloxypropanoic acids to afford optically active carboxylic acids and the corresponding esters with high enantioselectivities. Furthermore, theoretical calculations of the transition states required to form the chiral esters successfully proved the enantiomer recognition mechanism of the asymmetric esterification.
