This is a kind of colorless odour at normal temperatures and pressures and it is stable. As to its usage, it is usually used as the refrigerating fluid and be as the subsitutant of CFC-502 and HCFC-22. Besides, it could also be as the substitutes of Halon-1211 and Halon-1301 when as the extinguishant. Its product categories are mainly the refrigerants.
Being a kind of irritant chemical, it may cause inflammation to the skin or other mucous membranes.
So whiel dealing with it, you should be cautious. Do not breathe gas/fumes/vapour/spray (appropriate wording to be specified by the manufacturer). And if in case of insufficient ventilation wear suitable respiratory equipment.
Additionally, you could convert the following data information into the molecular structure:
SMILES:FC(F)C(F)(F)F
InChI:InChI=1/C2HF5/c3-1(4)2(5,6)7/h1H
