Quality Control

Every batch of 2-Methylpropyl 4-[4-(2,4-Difluorophenyl)Phenyl]-2-Methyl-4-Oxo-Butanoa Te is manufactured under strict quality management systems. We provide comprehensive analytical documentation to ensure traceability and batch-to-batch consistency. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request and are aligned with cGMP and ISO 9001 standards where applicable.

Storage

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