General Description
2-[4-(4-Methoxy-phenoxy)-phenyl]-malonic acid mono-(4-methoxy-phenyl) ester is a chemical compound categorized under the class of organic compounds known as diphenyl ethers. These are aromatic compounds containing two phenyl groups separated by an ether group. The 4-methoxy-phenoxy and 4-methoxy-phenyl functional groups indicate the presence of a methoxy group (-OCH3) attached to a phenol or phenyl ring. As a malonic acid mono-ester, it contains malonic acid, which is a dicarboxylic acid, partially esterified. The exact properties of this compound, such as its physical characteristics, reactivity, and uses, are not provided, and would require further specific scientific research.
Check Digit Verification of cas no
The CAS Registry Mumber 70175-90-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,1,7 and 5 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 70175-90:
(7*7)+(6*0)+(5*1)+(4*7)+(3*5)+(2*9)+(1*0)=115
115 % 10 = 5
So 70175-90-5 is a valid CAS Registry Number.

, (2018/04/03)
The invention relates to a method for synthesizing a latamoxef side chain. The method comprises the following steps: 1. dissolving p-hydroxyphenylacetic acid and p-methoxybenzyl alcohol in an inert solvent and using immobilized lipase to perform biocatalytic esterification in a reactor, and obtain a latamoxef side chain intermediate I after dewatering; 2. dissolving the latamoxef side chain intermediate I and p-methoxybenzyl alcohol in an inert solvent and using immobilized laccase to perform biocatalytic etherification to obtain a latamoxef side chain intermediate II; 3. subjecting the latamoxef side chain intermediate II to carbonylation to obtain the latamoxef side chain 4-(4-methoxybenzyloxy)phenylmalonic acid-4-methoxybenzyl monoester. The synthesis method solves the environmental protection problem of generating large amount of waste acid water and alkaline waste residues, and has the advantages of simultaneously reducing the energy consumption and the production cost, and increasing the yield and purity of the product.
