Quality Control

Every batch of (R)-Boroala-(+)-Pinanediol is produced and tested under strict quality management systems to ensure exceptional chiral purity and chemical integrity. Our products undergo rigorous analytical testing, including chiral HPLC, NMR, and GC, to guarantee compliance with customer specifications and industry standards. A comprehensive Certificate of Analysis (COA) detailing purity, enantiomeric excess, and impurity profiles is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (argon or nitrogen) after opening to prevent degradation.
