Nitrosobenzene

[586-96-9] C6H5NO (MW 107.11) InChI = 1S/C6H5NO/c8-7-6-4-2-1-3-5-6/h1-5H InChIKey = NLRKCXQQSUWLCH-UHFFFAOYSA-N (reagent used as hetero electrophile in various reactions) Physical Data: mp 65∼67 °C; bp 57∼59 °C/18 mmHg. Solubility: soluble in alcohol, benzene, and most organic solvents; insoluble in H2O. Form Supplied in: white or pale yellowish white solid. Purification: crystallization with acetone/H2O or ethanol/H2O. Handling, Storage, and Precautions: to help prevent decomposition, store in a refrigerator with direct light excluded. Nitrosobenzene should be used only in a well-ventilated fume hood because of its high volatility and stimulating smell. The toxicity of nitrosobenzene itself is unknown. Explodes at about 220 °C. Nitrosobenzene is oxidized to nitrobenzene on prolonged exposure to air.
