It is far less reactive than the other nitrogen trihalides nitrogen trichloride, nitrogen tribromide, and nitrogen triiodide, all of which are explosive. Alone among the nitrogen trihalides it has a negative enthalpy of formation. It is prepared in modern times both by direct reaction of ammonia and fluorine and by a variation of Ruff's method. [6]
Trifluoramine oxide was first discovered in 1966 independently by two different groups. One way to produce it was by an electric discharge in a mixture of oxygen on nitrogen trifluoride. Another even less yielding method is by reacting noble metal fluorides (IrF 6 or PtF 6) with nitric oxide. [1]
They are widely used in the electronics, cosmetics, and pharmaceutical industries, as well as in refrigeration when combined with other gases. PFCs were commonly used as fire extinguishants in the past and are still found in older fire protection systems. They are also a by-product of the aluminium smelting process.

Thiazyl fluoride, NSF, is a colourless, pungent gas at room temperature and condenses to a pale yellow liquid at 0.4 °C. [1] Along with thiazyl trifluoride, NSF 3, it is an important precursor to sulfur-nitrogen-fluorine compounds. It is notable for its extreme hygroscopicity.
An over-the-counter drug, its advertising was carried out by Warren Muller Dulubowsky. [3] By April 1989, Sterling Drug was owned by Eastman Kodak. Three Sterling brands, Haley's M-O, Philips' Milk of Magnesia, and Phisoderm, were being advertised by N.W. Ayer. [4] In 1991, the Phisoderm account was picked up by Ammirati & Puris of New York ...
