- CAS No.: 209995-38-0
- EINECS No.: N/A
- Molecular Formula: C8H5F3O2
- Molecular Weight: 190.12
- Chemical Classification: Fluorinated aromatic fine chemical, pharmaceutical intermediate, pesticide synthetic building block
- Core Product Features
High-purity fluorinated benzoacetic acid derivative; stable aromatic fluorine structure, high chemical inertness; contains reactive carboxyl group for esterification, amidation and condensation reactions; low residual fluorine impurities, widely used in new drug R&D, agrochemical synthesis and liquid crystal material production.
2. Detailed Physical & Chemical Properties
2.1 Physical Properties
- Appearance: White crystalline powder, uniform fine particles, no caking and foreign impurities
- Odor: Slight weak acid odor
- Solubility: Soluble in methanol, ethanol, acetone, ethyl acetate, dichloromethane; slightly soluble in hot water; insoluble in n-hexane and other aliphatic hydrocarbons
- Melting Point: 108–112℃
- Boiling Point: Decompose above 260℃, no fixed boiling point under normal pressure
- pH (saturated aqueous suspension): Weak acidity
- Hygroscopicity: Slightly hygroscopic, need sealed storage to avoid moisture absorption
2.2 Chemical Properties
- Fluorine Substitution Structure: Three fluorine atoms on benzene ring enhance metabolic stability of downstream drug molecules, improve lipid solubility
- Carboxyl Reactivity: Carboxyl group can react with alcohols, amines to generate ester and amide intermediates; can form salt with inorganic alkali
- Acid & Alkali Stability: Stable under neutral and weak acidic conditions; neutralized and dissolved in strong alkali aqueous solution; long-time strong alkali heating will cause partial defluorination degradation
- Photostability: Stable under indoor light; long-term strong ultraviolet exposure leads to slow oxidation discoloration
- Compatibility: Compatible with most conventional pharmaceutical solvents; incompatible with strong oxidants and strong reducing agents
3. Comprehensive Product Applications
3.1 Pharmaceutical Intermediate (Main Application)
Key fluorinated aromatic building block for synthesis of anti-inflammatory, anti-viral, anti-diabetic and central nervous system drugs. The trifluorophenyl structure can significantly improve drug cell membrane permeability and metabolic half-life, widely used in laboratory and pilot-scale pharmaceutical synthesis.
3.2 Agrochemical Intermediates
Raw material for high-efficiency low-toxicity herbicides, fungicides and insecticides; fluorinated aromatic groups improve pesticide absorption by crops and reduce environmental residue.
3.3 Liquid Crystal & Electronic Materials
Synthetic monomer for fluorinated liquid crystal compounds, used to adjust dielectric constant and low-temperature fluidity of liquid crystal mixtures.
3.4 Biochemical Research Reagents
Standard fluorinated aromatic reagent for organic synthesis labs, used for developing fluorine-containing probe molecules and enzyme inhibitors.
