4-NITROPHENYLARSONIC ACID Uses

4-Nitrophenylarsonic acid (CAS NO.98-72-6) is used as pharmaceutical intermediates, but also an analytical reagent.

4-NITROPHENYLARSONIC ACID Production

4-Nitrophenylarsonic acid (CAS NO.98-72-6) is derived by reaction of diazotization and arsenication of p-nitroaniline.
adding Nitroaniline into hydrochloric acid, stirring 2h, put ice cubes down to -5 °C,add sodium nitrite solution in 15min , stirring about 1h, obtaining diazonium salt solution. arsenic trioxide and sodium carbonate dissolved in water, cooling to 25 °C below, adding copper sulfate solution, and then adding the above-mentioned diazonium salt solution, the reaction temperature was controlled at 25°C below, generating 4-Nitrophenylarsonic acid (CAS NO.98-72-6) .
