1,1,1,2-Tetrafluoroethane as a pharmaceutical excipient for polymer porous microsphere filled column
Details of 1,1,1,2-tetrafluoroethane as a pharmaceutical excipient for the application of polymer porous microsphere filled column:
Pharmaceutical excipient tetrafluoroethane (HFC-134a)
1、 Basic information
Product name: medicinal excipient 1,1,1,2-tetrafluoroethane
Molecular formula: CH2FCF3
Relative molecular weight: 102.03
Product standard: G/JHGF O1 J 20 209-2012
2、 Physical and chemical properties: it is a colorless gas with slight ether odor under normal temperature and pressure; Melting point - 103.15 ℃, boiling point - 26.1 ℃, liquid density 1.206g/cm3 (25 ℃); Generally, they are compressed into liquid and stored in steel cylinders, and their thermal properties are similar to R12. Ozone depletion potential (ODP) is 0, and global warming potential (GWP) is 1200.
3、 Product use:
1,1,1,2-tetrafluoroethane is the main substitute for CFCs sprays. At the same time, due to its low toxicity and non-flammability, it has been developed as a carrier for drug inhalers (i.e. medical aerosols). Anti-asthmatic aerosol used to treat asthma, COPD (chro nic obstructive pulmo nary disease) and respiratory tract infection; Nasal aerosol foam aerosol for treating allergic rhinitis; Oral and local aerosols (such as promoting neurosensitivity, enhancing tooth vitality and relieving pain), etc.
