Piperazine type POPSO buffer

The Chinese name of POPSO is piperazine-N, N '- bis (2-hydroxypropane sulfonic acid), with CAS number 68189-43-5. It has the best buffering effect in the weakly alkaline range of 7.0-8.2 and can maintain the pH value of the solution in a stable state for a long time. The POPSO produced by our company is mainly reagent grade, and is often configured as buffer solution for environmental research, chemical analysis and biological research to regulate and stabilize the pH of the research solution. Piperazine family buffering agents POPSO POPSO buffer and PIPES, HEPES, POPSO, HEPPS, HEPPS, HEPPSO, HEPPSO, and HEPBS buffer belong to the same family of piperazines Family series. This series of buffering agents all contain piperazine rings and cannot react with various metals to form complexes and precipitate. However, they can undergo oxidation-reduction reactions with strong acids and bases. Therefore, when used, they need to be prepared and used immediately. At room temperature, high-quality POPSO is a white crystalline powder with very stable chemical properties. 0.25g of POPSO powder can be completely dissolved in 1ml of sodium hydroxide and reach saturation. The dissolved solution appears clear to slightly turbid. POPSO powder is almost insoluble in other organic solvents, so it does not affect biochemical reaction experiments when used as a buffer. In terms of molecular structure, POPSO is a dipole ion compound that carries both positive and negative charges simultaneously, namely a zwitterionic compound. At 25 ℃, the acidity coefficient of POPSO is 7.8 and does not change significantly with temperature changes. Adding non ionic inorganic salts to POPSO buffer will not change the activity coefficient of the solution. In general, POPSO buffering agents do not penetrate biofilms. POPSO can be used in cell culture media experiments that require metal cations, but it cannot be used in the study of mitochondria because POPSO has an inhibitory effect on the unidirectional channels of mitochondrial anions. Desheng is a professional source manufacturer of POPSO. With the efforts of scientific researchers, our company continuously improves the production process of POPSO powder, ensuring that the produced POPSO crystal powder is pure white with a purity of over 99%. In a 20% W/W sodium hydroxide solution, its UV and visible light absorbance is less than 0.1. Our company's commitment to customers is always to deliver on time with quality and quantity guaranteed.
