Specification
p-Phenylenediamine sulfate , its cas register number is 16245-77-5. It also can be called 1,4-Benzenediamine sulfate (1:1) ; Benzene-1,4-diammonium sulphate ; and HSDB 6256 . It is hazardous, so the first aid measures and others should be known. Such as: When on the skin: first, should flush skin with plenty of water immediately for at least 15 minutes while removing contaminated clothing. Secondly, get medical aid. Or in the eyes: Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Then get medical aid soon.

And as soon as to get medical aid. Then you have the ingesting of the product: Wash mouth out with water, and get medical aid immediately. Notes to physician: Treat supportively and symptomatically.
In addition, p-Phenylenediamine sulfate (CAS NO.16245-77-5) is not compatible with strong oxidizing agents, acids, acetic anhydride, acid chlorides, chloroformates, and you must not take it with incompatible materials, exposure to moist air or water. And also prevent it to broken down into hazardous decomposition products: Nitrogen oxides, carbon monoxide, carbon dioxide, sulfur oxides (SOx), including sulfur oxide and sulfur dioxide.
