2-Fluoroacrylic acid supplier CAS 430-99-9 zhishangbio

2-Fluoroacrylic acid (CAS number: 430-99-9) is a compound derived from the fluorination of acrylic acid, with the molecular formula C ₃ H ₃ FO ₂ and a molecular weight of 90.05 g/mol.
It modifies the molecular electronic structure by changing the α-hydrogen in acrylic acid with a fluorine atom, making the compound more reactive than unfluorinated acrylic acid. Its pKa is 2.68, less than that of acrylic acid at 4.25.
At space temperature level, 2-fluoroacrylic acid looks like a white to fade yellow crystalline powder. It has a melting point of 52 ° C and a boiling point of 181.3 ° C( at 760 mmHg). The substance is soluble in polar solvents, with a water solubility of 673 g/L at 25 ° C, and is miscible with methanol and ethanol.

AppsThis monomer is the basis for many high-value applications.

1. Synthesis of Fluoropolymers: 2-FLUOROACRYLIC ACIDS can be used as monomers to produce polymers that have excellent thermal stability, chemical resistance and low refractive indices (1.36–1.44).
2. Drug intermediates are used in the production of neuraminidase inhibitors and other drugs.
3. Optical products: The polymers obtained have excellent optical properties and are therefore suitable for use in optical fiber applications. 4. Weathering treatment, adhesives and prep work: Prepare surfaces for adhesives and durable finishes. Storage and handling 2-FLUOROACRYLIC ACIDS should be stored between 2–8 deg C, in a tightly-sealed container filled with an inert gas. Consider that It is important to avoid dampness or oxygen when working with 2-fluoroacrylic Acid. Wear safety goggles and gloves to avoid eye and skin damage.
