Description
It is usually used as the intermediate or raw material in the organic synthesis. For example, this chemical can be selected as the raw material to prepare three lanthanide metal organic frameworks (MOFs) with typical structural features of one-dimensional ladder-like chain, two-dimensional layer, and three-dimensional framework.1 Moreover, this substance is chosen as the reactant to fabricate new metal complexes with 5-(1H-imidazol-4-ylmethyl)aminoisophthalic acid, which have good electrocatalytic activities toward the reduction of H2O2 in phosphate buffer (pH=5.5) solution.2 In addition, as the active reactant, this chemical has been demonstrated to assist in the synthesis of a chiral, radically homopolymerizable methacrylamide dendrimer with eight ester groups.3

Check Digit Verification of cas no
The CAS Registry Mumber 99-31-0 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 9 and 9 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 99-31:
(4*9)+(3*9)+(2*3)+(1*1)=70
70 % 10 = 0
So 99-31-0 is a valid CAS Registry Number.

Cu nanorods and nanospheres and their excellent catalytic activity in chemoselective reduction of nitrobenzenes
Patra, Astam Kumar,Dutta, Arghya,Bhaumik, Asim
, p. 651 - 655 (2010)
Highly selective chemical route for the hydrothermal synthesis of Cu0 nanorods and nanospheres using a long chain saturated fatty acid, viz. lauric acid as template is reported. Our experimental results revealed Cu nanorods are of ca. 14 nm diameters and 100-235 nm length, whereas the nanospheres are of dimensions 2-15 nm diameter. Cu nanospheres show much enhanced catalytic activity over the nanorods for the chemoselective reduction of 4-nitrophenol and 5-nitroisophthalic acid to respective substituted anilines in one pot at room temperature, suggesting the role of particle size and shape in catalytic reduction.

The invention creatively provides a method for preparing high-purity 5-aminoisophthalic acid. The method is characterized in that 5-nitroisophthalic acid is used as the raw material, and nitryl is reduced through hydrazine hydrate/ raney nickel under the alkali condition; then the product is acidized with acetic acid until the pH is 3.5-4.0, and thus the high-purity 5-aminoisophthalic acid can be separated out. Compared with a currently publically reported preparation method, the preparation method has the advantages that the nitryl is reduced through hydrazine hydrate/raney nickel; the acetic acid is utilized for acidizing to separate out the product; the side reaction is few; the yield is high; the product purity is 99.5% or above; the operation is simple and convenient; the industrial production can be carried out.
