Reference Standards

Your confidence in your work is bolstered by your confidence in your standards. 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. We offer the only publicly available, official documentary standards for pharmaceutical ingredients in the USP-NF that link directly with a primary reference standard. When you use these standards together, you can be assured that your product meets compliance requirements and establish the quality benchmark against which you compare your results.
