This diester compound features a benzene ring with two carboxylate groups at positions 1 and 3, each linked to 4-ethenoxybutyl chains. With a molecular weight of 362.4 g/mol, it belongs to the class of aromatic diesters and exhibits skin sensitizing properties along with aquatic toxicity.

Bis(4-ethenoxybutyl) benzene-1,3-dicarboxylate is a liquid organic compound at room temperature due to its ester structure and molecular weight of 362.4 g/mol. The presence of vinyl ether groups (ethenoxybutyl chains) provides reactivity toward polymerization reactions. Its aromatic diester structure typically confers moderate viscosity and low volatility. The compound shows limited water solubility due to its hydrophobic aromatic core and long alkyl chains.

Bis(4-ethenoxybutyl) benzene-1,3-dicarboxylate serves as a crosslinking agent and reactive diluent in polymer applications. Its vinyl ether functionality makes it valuable for UV-curable coatings, adhesives, and composite materials. The compound acts as a plasticizer and flexibilizing agent in various polymer formulations. Industries utilize it in specialty coatings, printing inks, and advanced materials where controlled crosslinking and flexibility are required.

Bis(4-ethenoxybutyl) benzene-1,3-dicarboxylate requires careful handling due to its skin sensitizing properties (Skin Sens. 1). Wear appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. Ensure adequate ventilation to prevent vapor accumulation. Avoid direct skin and eye contact. Work in well-ventilated areas or use local exhaust ventilation. Follow Warning label precautions and have emergency eyewash stations readily available.

Bis(4-ethenoxybutyl) benzene-1,3-dicarboxylate should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from heat sources and direct sunlight. Keep away from strong oxidizing agents and incompatible materials. Due to its vinyl ether groups, store away from acids and moisture to prevent premature polymerization. Maintain storage temperatures below 25°C when possible and ensure containers are properly labeled according to GHS requirements.

Skin contact with bis(4-ethenoxybutyl) benzene-1,3-dicarboxylate requires immediate removal of contaminated clothing and thorough washing with soap and water for at least 15 minutes. For eye contact, rinse immediately with clean water for 15 minutes while holding eyelids open. If inhaled, move to fresh air immediately. Due to its sensitizing properties, seek medical attention if irritation persists or allergic reactions develop. Do not induce vomiting if ingested.

Bis(4-ethenoxybutyl) benzene-1,3-dicarboxylate disposal must comply with local and national hazardous waste regulations due to its aquatic toxicity classification. Contact licensed waste disposal companies for proper treatment and disposal. Do not discharge to drains, soil, or water bodies as it poses acute and chronic aquatic hazards. Small quantities can be incinerated at authorized facilities with appropriate emission controls. Always consult local environmental authorities for specific disposal requirements.

Bis(4-ethenoxybutyl) benzene-1,3-dicarboxylate is classified as ADR Class 9 (Miscellaneous dangerous goods), Packing Group III for transport purposes. Use appropriate UN-specification packaging suitable for Class 9 materials. Ensure packages are properly labeled with hazard labels and shipping documentation includes correct technical names and hazard information. Transport vehicles must comply with ADR requirements for Class 9 substances including proper placarding and emergency equipment.

Bis(4-ethenoxybutyl) benzene-1,3-dicarboxylate is subject to REACH registration requirements in the EU and must comply with CLP regulation for classification and labeling. While not currently listed as a Substance of Very High Concern (SVHC), its skin sensitizing and aquatic toxic properties require appropriate risk management measures. Users must follow occupational exposure guidelines and environmental protection measures. Industrial users should implement appropriate risk management strategies in their chemical safety reports.
