Sodium hexafluoroantimonate(1-)(CAS: 16925-25-0)

Sodium hexafluoroantimonate(1-) is a white crystalline solid with a molecular weight of approximately 267.08 g/mol. It is practically insoluble in water but soluble in organic solvents. The compound is highly reactive and can release toxic gases when heated or exposed to moisture. It reacts with water to produce hydrogen fluoride and sodium fluoride.

Sodium hexafluoroantimonate(1-) is synthesized by treating antimony pentafluoride with sodium in anhydrous ether. The reaction typically requires a platinum catalyst and is performed under an inert atmosphere. The yield and selectivity are high, making it a reliable synthetic method.

Sodium hexafluoroantimonate(1-) is used in the electronics industry for the fabrication of semiconductors, in the pharmaceutical industry for certain synthetic pathways, and in polymer industry for the synthesis of special polymers. It is also used in the production of sensors and as a reagent in analytical chemistry.

When handling Sodium hexafluoroantimonate(1-), appropriate personal protective equipment (PPE) is essential, including gloves, chemical-resistant lab coat, and safety goggles. The compound should be handled in a well-ventilated area or a fume hood to avoid inhalation of toxic gases. In case of a spill, it should be handled with caution using appropriate absorbent materials. Refer to the Safety Data Sheet (SDS) for detailed handling and disposal instructions.
