Quality Control

Our Hydroxynonyl-Benzenesulfonic Acid is manufactured under a strict quality management system to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including assay, impurity profiling, and physical property verification. Certificates of Analysis (COA) documenting purity, acidity, and other critical parameters are provided with every shipment to support your quality assurance protocols.

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) and a strong acid; containers must be kept tightly sealed to exclude moisture and stored separately from bases and reactive materials.
