Chemische Eigenschaften
yellow needles or powder
Verwenden
4-Nitrobenzoyl chloride is used in the preparation of polysubstituted furanonaphthoquinoines. It is also involved in Michael addition, Henry reaction, O-alkylation and cycloaddition reactions. Further, it is employed as an intermediate in active pharmaceutical ingredient and dyes.
Verwenden
4-Nitrobenzoyl Chloride is used inorganic syntheses such as Michael additions. Also used in the synthesis of polysubstituted furanonaphthoquinoines.
Allgemeine Beschreibung
Yellow needles or powder with a pungent odor.
Air & Water Reaktionen
Unstable in moist surroundings and should be kept in a tightly-closed container. React with water or steam .
Reaktivität anzeigen
4-Nitrobenzoyl chloride is incompatible with bases (including amines), with strong oxidizing agents, and with alcohols. May react with reducing agents. May react vigorously or explosively if mixed with diisopropyl ether or other ethers in the presence of trace amounts of metal salts [J. Haz. Mat., 1981, 4, 291].
Health Hazard
TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
Brandgefahr
Flash point data are not available for 4-Nitrobenzoyl chloride, but 4-Nitrobenzoyl chloride is combustible.
Sicherheitsprofil
Moderately toxic by ingestion. Experimental reproductive effects. Mutation data reported. When heated to decomposition it emits toxic fumes of NOx and Cl-. See also NITRO COhlPOUNDS OF AROMATIC HYDROCARBONS and CHLORIDES.
läuterung methode
Crystallise the acid chloride from dry pet ether (b 60-80o), *C6H6 or CCl4. Distil it under vacuum. Irritant. [Adama & Jenkins Org Synth Coll Vol I 394 1941, Beilstein 9 III 1709, 9 IV 1191.]
