Quality Control

Every batch of Neoorthosiphol A is produced and analyzed under strict quality management protocols. We provide comprehensive analytical documentation, including HPLC chromatograms and full spectroscopic data (NMR, MS), to verify identity and purity. A Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is supplied with each shipment to ensure compliance with research and development standards.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below for long-term stability. For daily use, allow the sealed vial to equilibrate to room temperature before opening to prevent moisture condensation. The compound should be stored in a cool, dry place away from strong acids and oxidizing agents.
