Quality Control

Our Benzeneacetic Acid, 4-(Bromomethyl)-α-Methyl-, Ethyl Ester is produced under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for assay and purity, GC for residual solvents, and NMR/IR for structural confirmation. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment. We adhere to cGMP guidelines where applicable to support our clients in regulated industries.

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 to prevent degradation from atmospheric moisture. Keep away from heat, sparks, and open flame.
