4-Nitrophenylhydrazine Usage And Synthesis
Chemical Properties white to light yellow crystal powder
Uses Analytical reagent (aldehydes, ketones).
Definition ChEBI: A member of the class of phenylhydrazines that is phenylhydrazine substituted at the 4-position by a nitro group.
General Description 4-Nitrophenylhydrazine is a orange-red leaflet or needles wetted with water. 4-Nitrophenylhydrazine will emit toxic oxides of nitrogen when heated to decomposition. 4-Nitrophenylhydrazine is slightly heavier than water and insoluble in water. 4-Nitrophenylhydrazine may be irritating to skin, eyes and mucous membranes. 4-Nitrophenylhydrazine may be toxic by ingestion. 4-Nitrophenylhydrazine may be explosive and sensitive to friction in the dry state. 4-Nitrophenylhydrazine is used as a reagent for ketones and aliphatic aldehydes.
Reactivity Profile 4-NITROPHENYLHYDRAZINE is a powerful explosive. 4-Nitrophenylhydrazine can SELF-IGNITE in the presence of contaminants. Auto-ignition temperature may vary for 4-nitrophenylhydrazine similar to that of hydrazine which has an autoignition of as low as 74oC in contact with iron rust. Dangerous fire hazard or severe explosion can occur when exposed to heat, flame or oxidizing agents. Severe explosion may also occur by chemical reaction with alkali metals; BaO; CaO; K; Na; NH3; Cl2; chromates; CuO; Cu++ salts; F2; H2O2; iron rust; metallic oxides; PbO2;Ni; Ni(ClO4)2; HNO3; N2O; O2; liquid O2; K2Cr2O7; Na2Cr2O7; tetryl; zinc diamide; Zn(C2H5)2. Dangerous; when heated to decomposition 4-Nitrophenylhydrazine emits highly toxic nitrogen compounds; may explode by heat or chemical reaction. (Sax and Lewis, 1987) under Hydrazine p. 538-539.
Health Hazard Some are toxic and may be fatal if inhaled, swallowed or absorbed through skin. Contact may cause burns to skin and eyes. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may cause pollution.
