ICH Q2(R1): Validation of Analytical Methods for Impurity Testing - Eurolabs Laboratory Testing Service

ICH Q2(R1) is a widely recognized international standard that governs the validation of analytical methods for impurity testing. The standard is published by the International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH), which brings together regulatory authorities and industry experts from around the world to develop harmonized standards.

Legal and Regulatory Framework

The ICH Q2(R1) standard is based on a combination of international and national regulations, including:

  • European Unions (EU) Directive 2009/109/EC

  • US Food and Drug Administrations (FDA) Guidance for Industry: Q2(R1)

  • International Organization for Standardization (ISO) standards (e.g., ISO 5725)

    • These regulatory frameworks require pharmaceutical manufacturers to validate their analytical methods to ensure the quality, safety, and efficacy of their products.

    Standard Development Organizations

    The ICH is a non-profit organization that brings together regulatory authorities and industry experts from around the world to develop harmonized standards. The ICH has a number of standard development organizations (SDOs) that contribute to the development of new standards, including:

  • US FDA

  • European Medicines Agency (EMA)

  • Japans Ministry of Health, Labour and Welfare

    • Evolution of Standards

    Standards evolve over time as technology advances and regulatory requirements change. The ICH Q2(R1) standard was revised in 2016 to reflect changes in analytical technologies and methods.

    Specific Standard Numbers and Scope

    The relevant standards for ICH Q2(R1) testing are:

  • ISO 5725: Calibration and testing of measurement gauges (1998)

  • ASTM E2554-08: Standard Guide for Validation of Analytical Methods

  • EN 45001: General requirements for the competence of testing and calibration laboratories

    • Standard Compliance Requirements

    Compliance with ICH Q2(R1) standards is mandatory for pharmaceutical manufacturers, contract research organizations (CROs), and contract manufacturing organizations (CMOs).

  • Pharmaceuticals: EU Directive 2009/109/EC

  • Food: FDA Guidance for Industry: Q2(R1)

  • Cosmetics: ISO 5725
