Grade Specifications

Maximum level of impurities: Insoluble matter 0.005%, Residue after ignition 0.01%, Cl 0.001%, SO<sub>4</sub> 0.005%, Heavy metals (as Pb) 5ppm, Fe 5ppm

Applications

It is used for etching of glass, preservation of food, in printing textile, and as mothproofing agent. It is used in chemical analysis and in brewing. It is used in the synthesis of NaHoF<sub>4</sub> and NaEuF<sub>4</sub>, which are important in solid state lasers as well as photoluminescence. The fluoride ion is used as a base and nucleophile in organic synthesis. Ammonium fluoride providee safe deprotection strategy for the tert-butyldimethylsilyl (TBS) group during RNA synthesis.

Notes

Hygroscopic and non-cumbustible. On heating, it sublimes and decomposes to HF and ammonia gas, which can recombine to form ammonium fluoride.
