CAS 75277-39-3

Sodium HEPES

Description:

Sodium HEPES, with the CAS number 75277-39-3, is a zwitterionic buffering agent commonly used in biological and biochemical research. It is a sodium salt of HEPES (4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid), which is known for its ability to maintain stable pH levels in biological systems, particularly in cell culture and enzyme assays. Sodium HEPES is soluble in water, making it easy to incorporate into various aqueous solutions. Its buffering range typically spans from pH 6.8 to 8.2, which is suitable for many physiological applications. The compound is non-toxic and generally well-tolerated by cells, making it a preferred choice for experiments involving living organisms. Additionally, it has low absorbance in the UV range, which is advantageous for spectrophotometric measurements. Overall, Sodium HEPES is valued for its effectiveness in stabilizing pH and supporting cellular functions in laboratory settings.
