Quality Control

Our 2-Isobutyl-2-Methyl-1,3-Propanediol is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay by GC/HPLC, identity confirmation (IR), and control of key impurities and moisture content. Certificates of Analysis (COA) documenting full compliance with agreed specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture.
