Overview
Macro-pored Silica Gel is a high-surface-area adsorbent produced via sol-gel processes, featuring interconnected pore networks for enhanced mass transfer. Its chemical structure consists of amorphous silicon dioxide (SiO₂), typically associated with CAS No. 7631-86-9.
Application
- Pharmaceuticals: Used in chromatographic separation of active pharmaceutical ingredients (APIs) and purification of antibiotics.
- Chemical Industry: Acts as a desiccant and catalyst support in petrochemical refining and organic synthesis.
- Laboratory Analysis: Serves as stationary phase in gas chromatography (GC) and liquid chromatography (LC).
Precautions
- Avoid inhalation of fine dust; use appropriate respiratory protection during handling.
- Store in sealed containers to prevent moisture absorption and maintain adsorption efficiency.
- Not intended for direct human ingestion or clinical administration.
