phyproof® Standards for USP Demands

The United States Pharmacopeia (USP) sets stringent guidelines for reference standards used for the testing of botanicals to ensure their quality, purity, and consistency. These requirements are critical for maintaining reliability in pharmaceutical, nutraceutical, and research applications involving phytochemicals. PhytoLab ensures that your compliance needs are met and is offering you an outstanding portfolio of highly purified phyproof® reference standards for your analysis according to USP requirements.

The key USP requirements for reference standards (RS) can be summarized as follows:

• Identification and Purity – RS must be accurately identified and characterized through validated analytical techniques, such as HPLC, GC, or MS to ensure the substance’s authenticity and high purity.
• Stability and Storage – RS must remain stable over time under specified conditions and carry proper labeling to indicate storage requirements and expiration dates.
• Documentation and Traceability – RS should be accompanied by Certificates of Analysis (CoA) detailing methods of analysis, purity, and batch traceability.
• Quantification and Potency – RS must align with USP monographs for potency and to ensure precise quantification.
• Good Manufacturing Practices (GMP) – RS must be produced under GMP, ensuring reproducibility and quality control.
