16484-77-8 Usage

Uses

Mecoprop-P has been used as a reference standard for identification of mecoprop enantiomer elution using chiral GC columns. It has also been used as a pesticide in a comparative study to detect the pesticide contamination of indoor air and human hair samples.

Definition

ChEBI: The (R)-enantiomer of 2-(4-chloro-2-methylphenoxy)propanoic acid; the active stereoisomer of the racemic herbicide mecoprop.

General Description

Mecoprop-P, a phenoxyalkanoic acid is widely used as herbicide. It forms colourless and odourless crystals. The (R)-isomer of mecoprop is the active herbicide site. It is generally used for postemergence control of broad-leaved weeds by translocating the herbicide to the roots.

Flammability and Explosibility

Notclassified

Check Digit Verification of cas no

The CAS Registry Mumber 16484-77-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,4,8 and 4 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 16484-77:
(7*1)+(6*6)+(5*4)+(4*8)+(3*4)+(2*7)+(1*7)=128
128 % 10 = 8
So 16484-77-8 is a valid CAS Registry Number.

HPLC separation of 2-aryloxycarboxylic acid enantiomers on chiral stationary phases

Charushin, V. N.,Chulakov, E. N.,Krasnov, V. P.,Levit, G. L.,Sadretdinova, L. Sh.,Tumashov, A. A.,Vakarov, S. A.

, p. 900 - 907 (2021/06/07)

The possibility for separating enantiomers of a number of practically significant 2-aryloxycarboxylic acids was studied by normal- and reversed-phase HPLC on popular chiral stationary phases. The best separation parameters were achieved on the chiral phases with the polysaccharide base Chiralcel OD-H and Chiralpack AD under the normal-phase HPLC conditions. The (S)- and (R)-enantiomers of 2-(1-naphthyloxy)- and 2-(2-iodophenoxy)propionic acids with enantiomeric excess ee >99% were isolated using preparative chiral HPLC.

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

Tengeiji, Atsushi,Nakata, Kenya,Ono, Keisuke,Shiina, Isamu

, p. 1227 - 1252 (2013/08/23)

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.

π-deficient 2-(arylsulfonyl)ethyl esters as protecting groups for carboxylic acids

Alonso, Diego A.,Nájera, Carmen,Varea, Montserrat

, p. 277 - 287 (2007/10/03)

Several π-deficient 2-(arylsulfonyl)ethyl groups have been studied as carboxylic acid protecting groups. The 2-[3,5-bis(trifluoromethyl)phenylsulfonyl]ethyl group is the most easily removed protecting group for acids under mild basic conditions using aqueous NaHCO3.
