Biological buffers play a crucial role in life science research. When comparing different buffer systems, succinate offers significant inherent advantages. Firstly, with pKa values of 4.2 and 5.6, succinate buffers provide excellent buffering capacity between pH 4.4 and 5.8. Secondly, unlike volatile acetic acid, it can be used in lyophilized (freeze-dried) products. Finally, succinate has been proven to have acceptable tolerability after in vivo administration.

Pfanstiehl offers both injectable-grade Succinic Acid (S-142) and Sodium Succinate Hexahydrate (D-161). Both products feature high purity, ultra-low endotoxins, and ultra-low residual metal impurities. Additionally, they undergo testing for residuals of various enzymes, such as DNase, RNase, phosphatase, and lipase, meeting the production requirements for biopharmaceuticals and vaccines. Currently, Pfanstiehl’s succinic acid and sodium succinate have completed DMF and CDE filings, and the CDE status of Sodium Succinate Hexahydrate (D-161) has been updated to "Category A".
