100-22-1 - Use
Open Data Verified Data
It can be used as an oxygen scavenger for boiler water in the field of water treatment. Its oxygen scavenging capacity is better than that of hydroquinone. Not only can be used in the boiler water, can also be added to the operation of the boiler water. Due to its high volatility, it can also be used for oxygen removal in boiler condensate water systems. It is also used as a developing aid for color photography and as a reagent for measuring the formaldehyde content in the air.

100-22-1 - Safety
Open Data Verified Data
pure N,N,N,N-tetramethylp-phenylenediamine, or its intermediate oxidation products, are toxic. Production, use of the product staff, should be protected.
