2-O-benzyl 1-O-butyl benzene-1,2-dicarboxylate

2-O-benzyl 1-O-butyl benzene-1,2-dicarboxylate is a phthalate ester compound with the molecular formula C19H20O4 and CAS number 85-68-7. This chemical substance has a molecular weight of 312.4 g/mol and belongs to the benzyl butyl phthalate family. It is classified as a reproductive toxicant category 1B and poses significant environmental hazards to aquatic life. The compound is regulated under various chemical safety frameworks due to its hazardous properties.

2-O-benzyl 1-O-butyl benzene-1,2-dicarboxylate is typically a clear to pale yellow oily liquid at room temperature with a characteristic mild odor. The compound has limited water solubility but dissolves readily in organic solvents such as alcohols, ethers, and aromatic hydrocarbons. Its molecular structure consists of a benzene ring with two ester substituents, contributing to its lipophilic nature and relatively high boiling point typical of phthalate esters.

2-O-benzyl 1-O-butyl benzene-1,2-dicarboxylate is primarily used as a plasticizer in polymer applications to increase flexibility and workability of plastic materials. It finds applications in the production of flexible PVC products, coatings, adhesives, and sealants. The compound may also serve as an intermediate in chemical synthesis processes. However, due to its reproductive toxicity classification and environmental concerns, its use is increasingly restricted in consumer products, particularly those intended for food contact or children's articles.

2-O-benzyl 1-O-butyl benzene-1,2-dicarboxylate requires careful handling due to its reproductive toxicity and environmental hazards. Essential personal protective equipment includes chemical-resistant gloves, safety goggles, and protective clothing. Work in well-ventilated areas or use local exhaust ventilation to minimize inhalation exposure. Avoid skin and eye contact, and prevent release to the environment. Pregnant workers should avoid exposure due to the substance's reproductive toxicity classification. Always wash hands thoroughly after handling.

2-O-benzyl 1-O-butyl benzene-1,2-dicarboxylate should be stored in tightly sealed original containers in a cool, dry, well-ventilated area away from heat sources and direct sunlight. Storage areas must have appropriate containment measures to prevent environmental release. Keep away from incompatible materials such as strong oxidizing agents and bases. Ensure storage areas are equipped with spill containment systems and maintain appropriate temperature controls to prevent degradation. Access should be restricted to trained personnel only.

Immediate action is required in case of contact with 2-O-benzyl 1-O-butyl benzene-1,2-dicarboxylate. For skin contact, remove contaminated clothing and wash affected area thoroughly with soap and water for at least 15 minutes. In case of eye contact, rinse immediately with plenty of clean water for 15 minutes and seek medical attention. If inhaled, move to fresh air immediately. For ingestion, do not induce vomiting and seek immediate medical attention. Always consult a physician if symptoms develop or persist.

2-O-benzyl 1-O-butyl benzene-1,2-dicarboxylate must be disposed of as hazardous waste according to local and national environmental regulations. The substance cannot be disposed of in regular waste streams due to its reproductive toxicity and aquatic toxicity. Contact licensed hazardous waste disposal companies for proper treatment and disposal. Incineration at high temperatures in approved facilities is typically the preferred disposal method. Ensure all disposal activities comply with waste classification codes and transport requirements for hazardous materials.

2-O-benzyl 1-O-butyl benzene-1,2-dicarboxylate is classified under ADR Class 9 (Miscellaneous dangerous substances), Packing Group III for transport purposes. This classification requires specific packaging, labeling, and documentation requirements for road transport. Packages must bear appropriate hazard labels and proper shipping names. Transport vehicles need placarding and drivers require ADR training certificates. Ensure compliance with quantity limitations and segregation requirements during transport. All transport documentation must include emergency response information.

2-O-benzyl 1-O-butyl benzene-1,2-dicarboxylate is subject to extensive regulatory oversight under REACH registration requirements and CLP classification as reproductive toxicant category 1B. The substance faces restrictions in various applications, particularly in consumer products and articles intended for children. Environmental regulations apply due to its aquatic toxicity classification. While not currently listed as an SVHC, its hazardous properties mean it may face future regulatory restrictions. Companies must comply with worker protection regulations and environmental discharge limits.
