Why 502BIO

Built on consistency, purity, and traceability

Research depends on materials you can trust batch after batch. We standardize every step — sourcing, synthesis, verification, and labeling — so what's on the certificate is what's in the vial.

  • Korean-made synthesis

    Produced at established Korean manufacturing partners with documented process control.

  • 99%+ HPLC purity

    Identity and purity verified analytically before a batch is released.

  • Lot-numbered vials

    Every unit carries a 502BIO-XXX-2026-001 lot for clean record-keeping.

Documentation

A certificate behind every batch

Purity claims should be verifiable. For each production lot we can provide a certificate of analysis, and the lot number printed on the vial ties the physical product back to its batch record.

  • Certificate of analysis

    Per-batch COA available on request for your documentation.

  • Handled cold & dark

    Lyophilized and stored to preserve integrity until reconstitution.

  • Clean presentation

    Consistent, professional vial labeling across the entire line.
