The Standard

Quality you can cite.

Each lot is characterized before it leaves our facility, and the data travels with it. No mystery powders, no missing paperwork — just traceable reagents and the records to back them.

  • HPLC
    Purity to the decimal. Reverse-phase HPLC with the chromatogram on file for every batch.
  • MS
    Identity confirmed. ESI mass spectrometry verifies molecular weight against the target sequence.
  • COA
    Batch-specific certificate. Lot number, test dates, methods, and results — included with every order.
  • 3RD
    Independent verification. Third-party assay reports available for published lots.
