1,4-Piperazinediethanesulfonic acid, sodium salt (1:2)

Description:
1,4-Piperazinediethanesulfonic acid, sodium salt (1:2), commonly referred to as PIPES, is a buffering agent widely used in biological and biochemical research. It is a zwitterionic compound, meaning it contains both positive and negative charges, which helps maintain a stable pH in solutions, typically in the range of 6.1 to 7.5. PIPES is particularly valued for its low absorbance in the ultraviolet region, making it suitable for spectroscopic applications. The sodium salt form enhances its solubility in aqueous solutions, facilitating its use in various laboratory settings. It is non-toxic and has minimal interference with biological processes, making it ideal for cell culture and enzyme assays. Additionally, PIPES is stable under a range of temperatures and conditions, contributing to its popularity as a buffer in molecular biology, biochemistry, and analytical chemistry. Its chemical structure includes a piperazine ring and sulfonic acid groups, which are responsible for its buffering capacity and ionic properties.
