75066-21-6 Usage
General Description
Propanoic acid, 2-Methyl-2-(2,4,6-triMethylphenoxy)- is a chemical compound that consists of propanoic acid and a methylphenol group. It is often used as a herbicide to control broadleaf weeds and brush in various crops and non-crop areas. Propanoic acid, 2-Methyl-2-(2,4,6-triMethylphenoxy)- is known for its selective action on certain types of weeds while being safe for use on desirable plants. It is commonly formulated as an emulsifiable concentrate or a water-soluble granule for easy application. Its mode of action involves the inhibition of an enzyme called acetolactate synthase, which is crucial for the biosynthesis of branched-chain amino acids in plants. Overall, propanoic acid, 2-Methyl-2-(2,4,6-triMethylphenoxy)- is a key ingredient in herbicides that effectively target unwanted vegetation.
Check Digit Verification of cas no
The CAS Registry Mumber 75066-21-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,0,6 and 6 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 75066-21:
(7*7)+(6*5)+(5*0)+(4*6)+(3*6)+(2*2)+(1*1)=126
126 % 10 = 6
So 75066-21-6 is a valid CAS Registry Number.

The Synthesis of 4-Methylcyclohexa-2,5-dienones from Phenols
Islam, M. Majharul,Waring, Anthony J.
, p. 768 - 783 (2007/10/02)
4-Alkyl phenols have been converted by a known sequence into 2-aryloxyisobutyric acids and thence, by bromination at the 4-position of the aromatic ring with concomitant intramolecular lactone formation, into masked 4-alkyl-4-bromocyclohexa-2,5-dienones.Reaction with lithium dimethylcuprate, as a model for other lithium dialkylcuprates, replaces the bromine by a methyl group.Hydrolytic demasking gives 4-alkyl-4-methylcyclohexa-2,5-dienones.The method should allow the general synthesis of 4-alkylated cyclohexa-2,5-dienones from phenols via a nucleophilic alkylation step.This contrasts with an existing route which uses electrophilic alkylation of phenols or phenoxide ions by a restricted range of reactive alkylating agents.
