Independent verification

Official Resources

Curated text links to accreditation bodies, standards organizations, regulators, and public chemical databases. Use these directories to verify laboratories and educate your team — not as proof that any supplier or batch is approved.

Six-step accreditation lookup

Follow this workflow when a supplier COA cites an accredited testing laboratory. Detailed field guidance is in How to Verify a Laboratory.

  1. Record the laboratory legal name

    Copy the full legal entity name exactly as printed on the test report or accreditation certificate. Avoid trading names unless they are explicitly linked to the accredited entity.

  2. Identify the accreditation body

    Note which national or regional accreditation body issued the certificate (for example CNAS, UKAS, A2LA, or ANAB). ILAC can help you find the correct body for the destination country.

  3. Open the official directory

    Use only the accreditation body’s official website or ILAC signatory search. Do not rely on screenshots, supplier-hosted PDFs, or third-party verification portals.

  4. Search the legal entity

    Search the directory using the legal name from the report. Confirm certificate status is current and that the listed site address matches the testing location if provided.

  5. Review the scope document

    Open the schedule or scope of accreditation and confirm the specific test method (for example HPLC peptide purity or LC-MS identity) applies to your matrix and analyte class.

  6. Document your findings

    Save the directory result, scope excerpt, and validity dates in your qualification file. Accreditation at the time of testing does not by itself prove a specific batch result.

Laboratory Accreditation & Scope Lookup

  • International Laboratory Accreditation Cooperation

    Commonly known as ILAC

    Region: Global · Last checked:

    ILAC provides a directory of accreditation body signatories to the ILAC MRA. Buyers can identify the relevant national accreditation body before searching that body’s official laboratory directory.

    How to use
    Start with the destination country, open the recognized accreditation body, then search for the laboratory legal name from the test report.
    Important caveat
    ILAC does not test products, issue product COAs, or approve suppliers.

  • China National Accreditation Service for Conformity Assessment

    Commonly known as CNAS

    Region: China · Last checked:

    Use CNAS directories to check whether a Chinese laboratory or conformity assessment body is accredited.

    How to use
    Search the laboratory legal name, then review the current scope document for the relevant chemical testing methods.
    Important caveat
    Accreditation must be checked against the specific scope, test object, and method — not assumed for all peptide tests.

  • United Kingdom Accreditation Service

    Commonly known as UKAS

    Region: United Kingdom · Last checked:

    Search UKAS-accredited laboratories and conformity assessment bodies.

    How to use
    Review certificate status, site address, and schedule of accreditation.
    Important caveat
    Check that the tested method appears in the current scope.

Analytical Methods & Pharmacopeia Resources

  • ISO/IEC 17025

    Region: Global · Last checked:

    ISO/IEC 17025 specifies requirements for the competence, impartiality, and consistent operation of testing and calibration laboratories.

    How to use
    Use as a reference when evaluating laboratory management systems alongside the accreditation body scope.
    Important caveat
    ISO/IEC 17025 is a laboratory competence standard — not a product certificate and not proof that every test is accredited.

  • ICH Quality Guidelines

    Commonly known as ICH

    Region: Global · Last checked:

    Quality guidelines covering analytical procedure development, validation, specifications, impurities, and stability.

    How to use
    Reference ICH Q2(R2), Q14, and Q6A when discussing method validation expectations with suppliers or labs.
    Important caveat
    Guidelines support pharmaceutical quality systems; they do not approve a research product or supplier.

  • USP Peptide Standards

    Commonly known as USP

    Region: United States · Last checked:

    Reference information on peptide standards and related methods.

    How to use
    Use for educational comparison of compendial expectations.
    Important caveat
    Reference to USP materials is not USP certification of a supplier or batch.

Regulatory Reference Materials

  • FDA Synthetic Peptide Guidance

    Commonly known as FDA

    Region: United States · Last checked:

    FDA guidance on synthetic peptide drug substance development and control.

    How to use
    Educational reference for analytical and CMC expectations in regulated contexts.
    Important caveat
    Guidance documents are not FDA approval of a supplier, research product, or laboratory.

  • EMA Synthetic Peptide Guideline

    Commonly known as EMA

    Region: European Union · Last checked:

    EMA scientific guideline on synthetic peptide development and control.

    How to use
    Reference for manufacturing, characterization, and specification discussions.
    Important caveat
    Partial alignment with guidance is not EMA certification.
