USP Reference Standards
Not all standards are created equal. We establish primary standards for helping to ensure quality in pharmaceutical development and manufacturing. To confirm accuracy and reproducibility, USP Reference Standards are rigorously tested and evaluated by multiple independent laboratories including USP, commercial, regulatory, and academic labs. We also provide publicly available, official documentary standards for pharmaceutical ingredients in the USP–NF that link directly with our primary reference standards.
When you use these standards together, you know you’re gaining value beyond the vial. Your peers agree; generic drug manufacturers surveyed believe that pharmacopeial standards:
- Accelerate product development, saving 19% of time, overall, and 31% of time on analytical method development
- Reduce risk of ANDA rejection, according to 90% of respondents
With USP Reference Standards you’re getting value beyond the vial. Feel confident that you’ve made the best decision.
