This EDOT dicarboxylic acid derivative is a key functional monomer and intermediate for synthesizing high-performance conductive polymer materials. It is mainly used for preparing modified PEDOT series conductive polymers, introducing carboxyl functional groups to greatly improve material water solubility, dispersibility and substrate adhesion. In electronic industry, it is widely applied in preparing transparent conductive films, flexible electrode materials and organic photoelectric devices, effectively enhancing the conductivity and environmental adaptability of finished products. It is also an important raw material for manufacturing supercapacitor electrode materials and lithium battery conductive additives, which can optimize ion transmission efficiency and improve battery cycle stability. In the field of sensor research, it can be used to develop high-sensitivity gas sensors and biological sensing elements, realizing efficient signal induction and rapid response. Besides, it serves as a building block for organic synthesis and new material development, and can be used to synthesize various functional conjugated polymers. With controllable molecular structure and excellent modifiability, it meets the research and production demands of flexible electronics, new energy batteries, photoelectric materials and intelligent sensing industries, and has broad application prospects in advanced electronic material manufacturing.

This product belongs to common organic chemical intermediate with mild irritation and low acute toxicity. Direct skin contact may cause slight dryness, itching and local redness, and long-term repeated contact may aggravate skin discomfort symptoms. When scattered dust floats in the air, inhalation will irritate nasal cavity and throat mucosa, causing dry throat, cough and other mild respiratory discomforts, and long-term high-concentration inhalation is not allowed. Once it splashes into eyes accidentally, it will cause obvious stinging sensation and conjunctival irritation, which needs timely cleaning. Accidental oral intake will easily induce nausea, stomach distension and other gastrointestinal adverse reactions. During all operating processes, staff must wear dust-proof masks, chemical protective gloves and safety goggles, and operate in well-ventilated environment. The finished products should be sealed and stored in cool, dry and dark places, kept away from fire sources, high heat and strong oxidizing substances, and strictly separated from food and daily supplies. In case of skin contact, wash repeatedly with plenty of soapy water; if eye contact occurs, flush continuously with running clear water for more than 15 minutes and seek medical treatment in time. All waste residues and waste liquid must be treated in accordance with industrial hazardous waste standards, and random dumping and discharge are forbidden to prevent pollution to soil and water body, so as to ensure personal operation safety and ecological environmental safety.
