  • Assured Quality – Partnering only with suppliers who follow strict international quality and regulatory guidelines.

  • Expert Guidance – A dedicated team to help select the most suitable PRS for your research or production needs.

  • Simplified Procurement – Efficient sourcing, documentation, and timely delivery for your business.

By working with Cleanchem Laboratories, you secure reliable, high-purity reference standards that ensure your medicines meet regulatory requirements and maintain patient safety.

Reference Standards: Everything You Need to Know

A reference standard is a highly purified and well-characterized material used to verify the identity, strength, quality, and purity of pharmaceutical substances, APIs, excipients, and finished products. Using reference standards, laboratories can prepare working standards for routine quality control.

Reference standards may be obtained from official sources such as USP, EP, BP, and IP, or prepared in-house with full traceability.

Key roles of reference standards include:

  • Supporting drug development at every stage.

  • Acting as a benchmark for evaluating processes and product performance.

  • Ensuring consistent quality, safety, and compliance with global regulations.

Types of Pharmaceutical Reference Standards

  1. Primary Reference Standards

    • Obtained from recognized pharmacopeial or certified sources.

    • Purity typically >95% with full analytical characterization (NMR, MS, IR, UV/VIS, HPLC, Karl Fischer, GC, etc.).

    • Used directly without further testing when stored under recommended conditions.

  2. Secondary Reference Standards

    • Prepared and qualified against a primary reference standard.

    • Each batch is tested, documented, and periodically requalified to ensure reliability.

  3. Pharmacopeial Reference Standards

    • Official standards from USP, EP, BP, IP.

    • Universally accepted and used according to pharmacopeial monographs.

    • Require no additional testing before use.

  4. Impurity Reference Standards

    • Specially characterized materials used to detect and quantify impurities.

    • Essential for method development, validation, and purity testing.

    • Identity, purity, and assay must be clearly defined.

Additional Categories of Reference Standards

  • Chemical Origin Standards – For APIs, excipients, and chemical impurities.

  • Biotechnological Origin Standards – For biologics, biosimilars, cell/gene therapy.

  • Herbal Reference Standards – For herbal and plant-based products.

  • Radiopharmaceutical Standards – For nuclear medicine applications.

  • Calibration Standards – For instrument validation under GMP compliance.

Handling, Storage, and Documentation

  • Reference materials must be stored under controlled temperature, humidity, and light conditions.

  • Proper sealing and labeling with batch number, analysis date, and expiry are mandatory.

  • Usage logs and traceability records must be maintained for compliance.

  • Shelf life and validity are determined based on stability data, usually ranging from 3 to 36 months depending on compound stability.

Conclusion

Cleanchem Laboratories provides access to a wide range of primary, secondary, pharmacopeial, and impurity reference standards to support pharmaceutical analysis and regulatory compliance.
