Quality Control

Our Crotonic Acid Isopropyl Ester is manufactured under strict quality management systems to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including assay, purity verification, and impurity profiling, to meet exacting customer requirements. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Recommended storage temperature is between 15°C and 25°C. Keep container tightly sealed when not in use to minimize moisture absorption and prevent volatilization.
