Specification:

The 1-Chloro-1,1-difluoroethane , with its chemical register number75-68-3, is also called as 1,1,1-chlorodifluoroethane ; 1-Chlor-1,1-difluorethan ; 1-chloro-1,1-difluoro ; 1-chloro-1,1-difluoro-ethan ; alpha-Chloroethylidene fluoride ; alpha-chloroethylidenefluoride ; CFC 142b;cfc142b .

The physical properties of this chemcial are as followings:(1)ACD/LogP:  1.33 ; (2)ACD/LogD (pH 5.5):  1.33  ; (3)ACD/LogD (pH 7.4):  1.33  ; (4)ACD/BCF (pH 5.5):  6  ; (5)ACD/BCF (pH 7.4):  6  ; (6)ACD/KOC (pH 5.5):  125.52  ; (7)ACD/KOC (pH 7.4):  125.52  ; (8)Index of Refraction:  1.316  ; (9)Molar Refractivity:  16.45 cm ; (10)Molar Volume:  83.8 cm; (11)Polarizability:  6.52 ×10-24 cm3  ; (12)Surface Tension:  14.7 dyne/cm  ; (13)Density:  1.198 g/cm3  ; (14)Enthalpy of Vaporization:  23.14 kJ/mol  ; (15)Vapour Pressure:  2470 mmHg at 25°C.

Being a kind of extremely flammable chemical, it has an extremely low flash point and boiling point, and gases that catch fire in contact with air. Besides, it is dangerous for the environment, for it may present an immediate or delayed danger to one or more components of the environment and it will be dangerous for the ozone layer. What's more, this chemical is irritant and will cause inflammation to the skin or other mucous membranes. So while dealing with this chemical, we should be very cautious. Wear eye/face protection and then refer to manufacturer/supplier for information on recovery/recycling.
 
This is a kind of transparent colorless liquid with no odour. And it is stable and incompatible with strong oxidizing agents, metals - use brass regulators, steel cylinders for storage. As for its usage, it is widely used in many ways, such as being the working medium for the air cooler in hot environment and as reaction medium for heat pump'working medium and temperature control instrument, and also being the intermediate for refrigerating fluid and rocket propellant. Besides, its product categories are including the followings: Industrial/Fine Chemicals;HCFC;refrigerants;Organics.

Additionally, you could convert the following data information into the molecular structure:
SMILES:ClC(F)(F)C
InChI:InChI=1/C2H3ClF2/c1-2(3,4)5/h1H3
