Quality Control

Our (2R)-(-)-1,1-Bis(4-Methoxyphenyl)-3-Methyl-1,2-Butanediamine is manufactured under strict quality systems to ensure batch-to-batch consistency and high enantiomeric purity. Each lot is supported by a comprehensive Certificate of Analysis (COA) detailing key parameters such as chiral purity, chemical purity, and identity. We adhere to cGMP principles where applicable to support our customers in regulated industries.

Storage

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