WebIt is often prepared and used as a hydrochloride salt (TCEP-HCl) with a molecular weight of 286.65 gram/mol. It is soluble in water and available as a stabilized solution at neutral pH and immobilized onto an agarose support to facilitate removal of the reducing agent. Applications [ edit] WebSolubility • The hydrochloride salt (TCEP•HCl, MW 286.65) has a solubility in water of 310g/L (1.08M). Being hydrophilic, TCEP is generally very soluble in aqueous buffers at nearly any pH. Therefore, working concentrations and 10X stock solutions may be readily prepared in most aqueous buffers (see subsequent points about stability). notice of entry california
