Description
- General description: Potassium sodium tartrate tetrahydrate is a ferroelectric crystal[1] with a high piezoelectric effect and electromechanical coupling coefficient.[2]
- Application: Potassium sodium tartrate tetrahydrate has been used in the preparation of Lowry reagent for the determination of microsomal protein concentration in rat hepatic microsomes by Lowry method.[3] It may be used as a constituent to prepare DNS (3,5- dinitrosalicylic acid) reagent and Fehling′s solution B, which are used in the determination of reducing sugar.[4][5]
