Sodium perborate is also used as an oxidizing reagent in organic synthesis. For example, it converts thioethers into sulfoxides and sulfones. [16] Another use of sodium perborate in organic synthesis is as a convenient alternative to H 2 O 2, for example in the 2 step conversion of an aryl halide to a phenol (the first step is a Miyaura ...
The hydrated tetraborate anion occurs in the mineral borax (sodium tetraborate octahydrate) with the formula Na 2 [B 4 O 5 (OH) 4]·8H 2 O. The borax chemical formula is also commonly written in a more compact notation as Na 2 B 4 O 7 ·10H 2 O. Sodium borate can be obtained in high purity and so can be used to make a standard solution in ...
Disodium octaborate tetrahydrate Na 2 B 8 O 13 ·4H 2 O (commonly abbreviated DOT) is used as a wood preservative or fungicide. Zinc borate is used as a flame retardant . Some borates with large anions and multiple cations, like K 2 Al 2 B 2 O 7 and Cs 3 Zn 6 B 9 O 21 have been considered for applications in nonlinear optics .

Sodium borate is a generic name for any salt of sodium with an anion consisting of boron and oxygen, and possibly hydrogen, or any hydrate thereof. It can be seen as a hydrated sodium salt of the appropriate boroxy acid , although the latter may not be a stable compound.
Berberine, a plant compound traditionally used in herbal medicine, is today commonly stocked on the shelves of health food stores and pharmacies as a supplement. Beyond weight loss, berberine also ...
Yalda Night, or Shab-e Yalda (also spelled Shabe Yalda), marks the longest night of the year in Iran and in many other Central Asian and Middle Eastern countries. On the winter solstice, in a ...
