p-Phenylenediamine (PPD)
CAS No.: 106-50-3
Molecular Formula: C6H8N2 Molecular Weight: 108.14
Structural Formula:
Properties:
PPD is white to dust crystal at room temperature which has a slight aromatic odor. It is a strong oxidizing agent, soluble in water, alcohol, and ether and only slightly soluble in chloroform. PPD is sensitive to air and/or moisture, and the presence of either tends to hasten color deterioration. It may darken on storage. Melting point 142 ℃ (288 ℉) and boiling point of 274 ℃ (525 ℉) (at 1,013 hPa).

Usage:
PPD is generally used in industrial processing, and can be used as a precursor to aramid polymers and fibers and polyimid polymers and films, dyes and pigments. PPD is selected for the outstanding properties it imparts, including high temperature stability, high strength, and chemical and electrical resistance.
Package:
Iron drum lined with PE bag.
