CAS 103-47-9: 2-(Cyclohexylamino)ethanesulfonic acid

Description:2-(Cyclohexylamino)ethanesulfonic acid, commonly referred to as CHES, is a zwitterionic buffer widely used in biochemical and biological research. It features a cyclohexyl group attached to an amino group, which is further linked to an ethanesulfonic acid moiety. This structure imparts unique properties, including a high buffering capacity in the physiological pH range, making it suitable for maintaining stable pH conditions in various experimental setups. CHES is soluble in water, allowing for easy preparation of buffer solutions. Its pKa value is typically around 9.5, which enables effective buffering in alkaline conditions. Additionally, CHES is known for its low toxicity and minimal interference with biological systems, making it a preferred choice in cell culture and enzyme assays. The compound is stable under a variety of conditions, although it should be stored properly to prevent degradation. Overall, CHES is a valuable tool in laboratories for applications requiring precise pH control.
