QC

Our compounds undergo strict quality control by HPLC and/or NMR for each delivered compound to confirm sample identity and purity. We provide compounds of at least 95% purity, validated by NMR and/or HPLC.

The analytical data LC-MS, 13C-NMR, 1D-NMR, 2D-NMR, MS, CD and X-ray spectra are provided on demand of a customer.

BioBioPha Co., Ltd. conducts quality control of all compounds we offer on a regular basis to confirm stability and shelf life.

Correctness of structures is no less a level than published in the authoritative academic journals in this field. Interpretation of spectra and final approval of each compound are executed by a dedicated group of Ph.D. analytical chemists within BioBioPha.

• Bruker AV 800 MHz and Bruker Avance III 600 MHz NMR spectrometers;
• API QSTAR Pulsar and Bruker Esquire HCT 3000 mass spectrometers;
• Agilent 1200 series HPLC system, Waters 2535 series HPLC system and Büchi Sepacore MPLC system;
