USP Monograph Testing

The USP establishes primary standards for ensuring quality in pharmaceutical development & manufacturing.

USP Reference Standards are rigorously tested and evaluated by multiple independent commercial, regulatory, and academic laboratories to confirm accuracy and reproducibility.

USP Tests

Below are the most common general chapter tests we perform. We also perform many analyses by partial or full monographs in the official USP.
