2-Methoxysuccinic acid dimethyl ester is an organic compound with the chemical formula C6H10O5. It is a colorless liquid that is soluble in water and various organic solvents. This ester is derived from 2-methoxysuccinic acid, where the hydroxyl group is replaced by a methoxy group, and the carboxylic acid group is esterified with two methyl groups. It is synthesized through the reaction of 2-methoxysuccinic acid with methanol in the presence of an acid catalyst. 2-Methoxysuccinic acid dimethyl ester is used as an intermediate in the synthesis of various pharmaceuticals, agrochemicals, and other specialty chemicals due to its unique functional groups and reactivity.

4148-97-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4148-97-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,4 and 8 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 4148-97:
(6*4)+(5*1)+(4*4)+(3*8)+(2*9)+(1*7)=94
94 % 10 = 4
So 4148-97-4 is a valid CAS Registry Number.

Method of selectively catalytically oxidizing biomass-based furan compound

-

Paragraph 0110-0113, (2017/07/19)

The invention discloses a method of selectively catalytically oxidizing a biomass-based furan compound. The method comprises the following step of: by taking a heteropolyacid functional ionic liquid as a catalyst and an alcohol solution as a reaction medium, obtaining dicarboxylic acid or dicarboxylate in the conditions that the reaction temperature is 100-150 DEG C, the reaction time is 1-3h and the oxygen pressure is 0.5-1.0MPa, wherein over 62.35% of difumarate selectivity is obtained. The single chemical yield and selectivity for oxidizing preparation of a biomass-based furan derivative are far higher than those of the prior art. The method has the remarkable advantage that an ionic liquid catalyst can be recovered and recycled by simply adjusting the temperature. The method disclosed by the invention is mild in reaction condition, green and safe in process and simple to operate, and can realize intermittent and continuous production.
