Quality Control

Our production of Strontium 3-Hydroxy-4-[[1-(Sulphonatomethyl)-2-Naphthyl]Azo]-2-Naphthoate adheres to stringent quality management protocols to ensure batch-to-batch consistency and purity. All materials are subjected to rigorous analytical testing, including HPLC for purity and spectrophotometry for color strength verification. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture. Keep away from incompatible materials.
