Purolite C115HMR is a weak acid carboxylic cation exchange resin powder in the hydrogen form. Its special chemical structure confers exceptional properties in combination with absolute freedom from toxicity. The very weakly acidic carboxylic groups (pKNa= 5.5-6.0) make it ideal for the uptake of many complex bases including drugs with basic properties. This can help in the separation and purification, loading of these compounds, and offer slow release in use. Purolite C115HMR is delivered as a free flowing powder with a low total moisture content specially treated to contain low levels of extractibles. These properties make it ideal for pharmaceutical applications, when used in accordance with FDA recommended procedures for this type of product.
