Quality Control

Our Naphthalene Trisulfonic Acid, Sodium Salt is produced under a stringent quality management system to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including assay, impurity profile, and physical characterization, to meet exacting customer specifications. Certificates of Analysis (COA) documenting purity, identity, and other critical parameters are available upon request 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 product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect quality and handling properties.
