The Latest USP <467> Class 2 Residual Solvents for Pharma Analysis  

Restek, (USA) is a long-time partner of pharmaceutical QC labs performing residual solvent analysis, and our support continues with the release of an updated Class 2 Mix A reference standard. This standard has been reformulated to include cumene, which was added to the USP Class 2 list in August 2013, and allows labs to successfully detect and quantify solvent residues in compliance with the latest USP <467> guidelines.

As with Restek's other USP <467> mixes, this standard is prepared with the superior quality and reliability you have come to expect from Restek. It is quantitatively tested to confirm composition and stability, and detailed documentation is provided. In addition, being manufactured and QC-tested in Restek’s ISO-accredited labs means this standard will also help satisfy strict ISO requirements for the use of certified reference materials (CRMs).
