Specification:

The Potassium fluoride, with its?CAS registry number 7789-23-3, is a kind of white powder or crystals with a sharp saline taste. This chemical is hygroscopic and stable but incompatible with strong acids, strong bases. Besides, it is easily soluble in water, hydrofluoric acid and liquid ammonia and slightly soluble in alcohol and acetone.

The characteristics of this chemical are as below: (1)H-Bond Acceptor: 1; (2)Exact Mass: 57.96211; (3)MonoIsotopic Mass: 57.96211; (4)Heavy Atom Count: 2; (5)Complexity: 2; (6)Covalently-Bonded Unit Count: 2; (7)Density: 2.48; (8)Melting point: 860 oC; (9)Boiling point: 1505 oC; (10)Water solubility: 92.3 g/100 mL (18 oC).

As to its usage, it is widely applied in many ways. It could be used for etching a variety of glass and welding flux. It is also used as a wood preservative, pesticide and agricultural pesticide intermediate as well as a pharmaceutical industrial raw material and organic fluorinated material.

When you are dealing with this chemical, you should be cautious. For being a kind of toxic chemical, it may at low levels cause damage to health and it is harmful if by inhalation, in contact with skin and if swallowed. Therefore, if in case of contact with eyes, rinse immediately with plenty of water and seek medical advice, and if in case of accident or if you feel unwell, seek medical advice immediately (show the label where possible).

Additionally, you could convert the following datas into the molecular structure:
(1)Canonical SMILES: [F-].[K+]
(2)InChI: InChI=1S/FH.K/h1H;/q;+1/p-1
(3)InChIKey: NROKBHXJSPEDAR-UHFFFAOYSA-M?
