Quality Control

Our 2-Bromo-3-Methyl-n-Phenylbutanamide is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity suitable for research and commercial synthesis. Each lot undergoes comprehensive analytical testing, including HPLC, NMR, and GC-MS, to confirm identity and purity. Certificates of Analysis (COA) detailing all test results are provided with every shipment to support your quality assurance and regulatory documentation needs.

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 and may require storage under an inert atmosphere for long-term stability. Keep away from heat, sparks, and open flame.
