CAS No 18996-35-5
Application / Uses Preparation
As a weak acid, citrate can be used as a component in buffer solutions, including the commonly used SSC 20X hybridization buffer. This buffer uses sodium citrate and sodium chloride to maintain a neutral 7.0 pH. Other buffers may use a mixture of sodium citrate and citric acid – canonical buffer tables compiled for biochemical studies describe solutions of citrate and acid for buffer pHs of between 3.0 and 6.2.
