Quality Control

We supply 3-Buten-2-One, 4-Methoxy-3-Methyl-, (Z)- (9Ci) in high-purity grades suitable for demanding synthetic applications. Every batch undergoes rigorous analytical testing, including chiral purity assessment by HPLC and GC, to ensure consistent quality and stereochemical integrity. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment. Our quality management system supports compliance with cGMP and ISO standards for traceability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). Keep away from heat, sparks, and open flames. Due to its light-sensitive nature, containers should be kept in amber glass or opaque packaging during storage and handling.
