PIPES, Free Acid (CAS 5625-37-6)

Uso :

• This product is a high quality reagent, but has not been evaluated for use in cell culture. Please employ appropriate contaminant testing and/or sterilization techniques for the intended application.


• PIPES free acid is not very soluble in water (only 1 g per L at 100°C)1, but its salts are very soluble in water at the pH normally used as a buffer. PIPES will form a clear, colorless solution in 1 N NaOH, and is soluble to 20% (w/w) in 1 N NaOH. PIPES becomes soluble as the pH rises above pH 7 (it is converted to the salt form).
