2,2-Difluoro-1-propanol(CAS: 33420-52-9)

2,2-Difluoro-1-propanol has a crystalline form and a molecular weight of approximately 120.02 g/mol. It is slightly soluble in water but miscible with many organic solvents. The compound is moderately reactive, particularly towards nucleophiles and reducing agents. Its specific gravity is around 1.19 g/cm³ at 20°C. It is used in synthesis as a precursor for various fluorinated compounds due to its reactivity and stability under certain conditions.

2,2-Difluoro-1-propanol is commonly synthesized via the reaction of acetone with hydrogen fluoride (HF) in the presence of a phase transfer catalyst like tetrabutylammonium fluoride (TBAF). This process typically involves a one-pot reaction under anhydrous conditions. The yield is generally high, and the selectivity is good for the desired product. The reaction is exothermic and requires careful temperature control to avoid side reactions.

2,2-Difluoro-1-propanol is widely used in the pharmaceutical industry for the synthesis of fluorinated drugs due to its reactivity. It is also utilized in the polymer industry for the production of fluorinated polymers with enhanced properties. Additionally, the compound is employed in the sensor industry for its sensitivity to specific analytes and in the semiconductor industry for its use in etching and cleaning processes.

When handling 2,2-Difluoro-1-propanol, it is crucial to use appropriate personal protective equipment (PPE), including gloves, goggles, and a lab coat. The compound should be stored in a cool, dry place away from heat sources. Fume hoods should be used during handling to minimize exposure. In case of spillage, the area should be immediately cleaned up with appropriate absorbents, and the SDS (Safety Data Sheet) should be consulted for specific cleanup procedures. The compound is not a major fire hazard but should be handled with care due to its volatility and reactivity.
