Phenylhydrazine hydrochloride is used as a selective mannosidase inhibitor. It is used in the study of tyrosine phosphorylation of janus protein tyrosine kinase in the EPO-responsive normal erythroblastoid cells of anemic mice. It is used in steroid assays and as an N-protecting reagent. Its free base, phenylhydrazine is used to prepare indoles, which find application as intermediates in the synthesis of various dyes and pharmaceuticals.?? ??
White to tan solid with a weak aromatic odor.??? ?? ??
Forms corrosive acidic solutions.?? ???
Phenylhydrazine hydrochloride may be corrosive to metals [USCG, 1999].????
Phenylhydrazine hydrochloride is poisonous if swallowed or if fumes are inhaled. Dust is irritating to eyes, nose, and throat. Phenylhydrazine is a chronic poison. Phenylhydrazine is an industrial substance suspect of carcinogenic potential for humans.????
Toxic and irritating hydrogen chloride and oxides of nitrogen may be produced in fire. May be corrosive to metals. Hazardous polymerization may not occur.Safety Profile
Poison by ingestion, intraperitoneal, and subcutaneous routes. Experimental reproductive effects. Questionable carcinogen with experimental neoplastigenic and tumorigenic data. Mutation data reported. When heated to decomposition it emits very toxic fumes of NOx and HCl.??? ??
Phenylhydrazine hydrochloride is a widely used reagent in conjunction with sugars, aldehydes, and ketones. In addition, to its use in the synthesis of dyes; pharmaceuticals, such as antipyrin; cryogenin, and pyramidone; and other organic chemicals. The hydrochloride salt is used in the treatment of polycythemia vera.?? ??
UN2572 Phenylhydrazine, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.Purification Methods
Dissolve 100g of phenylhydrazine hydrochloride in 200mL of warm H2O (60-70o) during 1-3hours, then add 1L of boiling EtOH. The solution is filtered, while still hot, through Whatman No 2 filter paper and cooled in a refrigerator. The precipitate is collected on a medium sintered-glass filter and recrystallised twice this way, then washed with cold EtOH, dried thoroughly and stored in a stoppered brown bottle. [Peterson et al. Anal Chem 29 144 1957.] Hough, Powell and Woods [J Chem Soc 4799 1956] boiled the hydrochloride with three times its weight of water, filtered hot (charcoal), added one-third volume of concentrated HCl and cooled to 0o. The crystals were washed with acetone, and dried over P2O5 under vacuum. The salt has also been crystallised from 95% EtOH, and it can be sublimed. [Coleman Org Synth Coll Vol I 442 1941, Beilstein 15 III 71.]? ???
Phenylhydrazine is very reactive with carbonyl compounds, strong oxidizers; strong bases; alkali metals; ammonia, lead dioxide (violent). Attacks copper salts, nickel, and chromates.??? ??
Controlled incineration whereby oxides of nitrogen are removed from the effluent gas by scrubber, catalytic or thermal device.??????? ????? ?? ?? ? ???
