Quality Control

Our Benzenesulfonic Acid, 2-Bromo-5-Methyl-, Sodium Salt is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation (IR, NMR), to ensure it meets exacting specifications for use in sensitive applications. Certificates of Analysis (COA) documenting all critical quality attributes are available upon request to support your regulatory and quality assurance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
