Product Description:
Meso - Butane - 1,2,3,4 - tetracarboxylic dianhydride is a white to off - white crystalline solid. Structurally, it has a butane backbone with two five - membered anhydride rings formed by internal dehydration of four initial carboxyl groups.?
It's insoluble in non - polar solvents but soluble in polar ones like acetone, DMF, and DMSO. Highly water - sensitive, it hydrolyzes rapidly to carboxylic acids upon exposure to moisture. Stable when dry, high temps or strong acids/bases can decompose it.?
In organic synthesis, it's a key building block for making complex molecules. In materials science, it improves polymer thermal stability, strength, and chemical resistance. In pharma, it may be an intermediate for bioactive compounds. Store it cool, dry, away from light, moisture, and strong chemicals.
Application:
Meso - Butane - 1,2,3,4 - tetracarboxylic dianhydride is a key building block in organic synthesis. It reacts with nucleophiles like alcohols to form esters and with amines to form imides, facilitating complex molecule synthesis. In materials science, it enhances polymer properties such as thermal stability, mechanical strength, and chemical resistance by creating cross - linked structures during polymerization. In pharma, it may be used as an intermediate for synthesizing some bioactive compounds.
Package: 25kg/drum or bag
Storage: Sealed in dry, room temperature.
Executive Standards: International Standard.
