Description

Descrição geral

Potassium chloride is an inorganic salt commonly used in fertilizer industry. Its generation via chlorination of microcline has been reported.[1] The intrinsic and extrinsic conductivity of KCl crystals have been measured.[2] The impact of KCl on the activity of mitochondrial membrane, cristae and matrix proteins has been investigated.[3] It facilitates the preparation of isoxazolines in aqueous medium.[4]

Aplicação

Potassium chloride has been used in the preparation of the following:

• Amorphous calcium phosphate (ACP) deposition solution, used for ACP coating on Ti coupons.[5]
• Modified methylene blue (MB) solution, utilized in the MB two-phase titration method.[6]
• 4-(2-Hydroxyethyl)-1-piperazineethanesulfonic acid (HEPES)-containing artificial cerebrospinal fluid (ACSF) solutions.[7]
• Artificial sea water.[8]

May be used for the preparation of phosphate buffered saline, and for the extraction and solubilization of proteins.
