This substance is commonly called "commercial ammonium fluoride". The word "neutral" is sometimes added to "ammonium fluoride" to represent the neutral salt [NH 4]F as opposed to the "acid salt" (NH 4 HF 2). The acid salt is usually used in preference to the neutral salt in the etching of glass and related silicates. This property is shared ...
Chemical formula Synonyms CAS number C 10 H 16 N 2 O 8: Ethylenediaminetetraacetic acid (EDTA): 6381–92–6 C 12 H 22 O 11: sucrose: 57–50–1 C 18 H 29 O 3 S: sodium dodecyl benzenesulfonate: 2155–30–0
Tetra-n-butylammonium fluoride, commonly abbreviated to TBAF and n-Bu 4 NF, is a quaternary ammonium salt with the chemical formula (CH 3 CH 2 CH 2 CH 2) 4 N + F −. It is commercially available as the white solid trihydrate and as a solution in tetrahydrofuran. TBAF is used as a source of fluoride ion in organic solvents. [1]
Ammonium bifluoride, as its name indicates, contains an ammonium cation ([NH 4] +), and a bifluoride (or hydrogen difluoride) anion ([HF 2] −).The triatomic bifluoride anion features a strong three-center four-electron bond (specifically, a symmetrical hydrogen bond) with a bond energy greater than 155 kJ/mol, [2] and an H-F length of 114 pm.

tetrabutylammonium fluoride, a desilylation reagent. tetrabutylammonium bromide, a precursor to other tetrabutylammonium salts via salt metathesis reactions. tetrabutylammonium iodide, a low cost catalyst. [1] tetrabutylammonium triiodide, a common carrier of the triiodide anion used in chemical synthesis.
Ammonium fluorosilicate (also known as ammonium hexafluorosilicate, ammonium fluosilicate or ammonium silicofluoride) has the formula (NH 4) 2 SiF 6. It is a toxic chemical, like all salts of fluorosilicic acid. [4] It is made of white crystals, [5] which have at least three polymorphs [6] and appears in nature as rare minerals cryptohalite or ...
Buffered oxide etch (BOE), also known as buffered HF or BHF, is a wet etchant used in microfabrication. It is a mixture of a buffering agent, such as ammonium fluoride NH 4 F, and hydrofluoric acid (HF). Its primary use is in etching thin films of silicon nitride (Si 3 N 4) or silicon dioxide (SiO 2), by the reaction: SiO 2 + 4HF + 2NH 4 F → ...
Most other soluble salts of fluoride are in fact bifluorides, HF 2 –. Historically, there have been two main approaches to prepare tetramethylammonium fluoride: hydrofluoric acid neutralization of tetramethylammonium hydroxide, and salt metathesis between different ammonium salts and inorganic fluoride sources, such as KF or CsF.
