Abstract

Aminas y derivados de aminas que mejoran el rango de tamponado, y/o reducen la quelación y otras interacciones negativas del tampón y el sistema a ser tamponado. La reacción de aminas o poliaminas con varias moléculas para formar poliaminas con diferentes pKa extenderán el rango de tamponado. Los derivados que resultan en tampones zwitteriónicos mejoran el rendimiento al permitir un mayor rango de estabilidad.Amines and amine derivatives that improve the buffering rate, and / or reduce chelation and other negative interactions of the buffer and the system to be buffered. The reaction of amines or polyamines with various molecules to form polyamines with different pKa will extend the buffering range. Derivatives that result in zwitterionic buffers improve performance by allowing a greater range of stability.
