Description

2-Butenoic Acid, 2-Ethylhexyl Ester, (2E)- is a high-purity, unsaturated ester derivative of 2-butenoic acid, also known as trans-crotonic acid. This compound serves as a versatile chemical intermediate and a reactive monomer, valued for its ability to introduce specific functional groups and modify polymer properties. It is primarily sought by manufacturers in the polymer, specialty chemical, and lubricant additive industries for applications requiring controlled reactivity and specific ester functionality.

Application

• Polymer Modification: Acts as a reactive comonomer in the production of specialty polymers, including acrylic resins and polyvinyl acetate derivatives, to enhance flexibility, adhesion, or weatherability.
• Synthetic Lubricant Formulation: Used as a base stock or additive component in the synthesis of synthetic esters for high-performance lubricants and functional fluids.
• Chemical Intermediate: Serves as a key building block in organic synthesis for pharmaceuticals, agrochemicals, and fine chemicals, undergoing reactions such as hydrolysis, transesterification, or Michael addition.
• Plasticizer Production: Employed in the manufacture of polymer plasticizers to improve the processability and durability of PVC and other plastics.
• Surface Coating Resins: Incorporated into alkyd resins and other coating formulations to adjust drying times, hardness, and chemical resistance.
• Adhesive & Sealant Formulations: Utilized to modify the tack, peel strength, and curing profile of industrial adhesives and sealants.

Quality Control

Our 2-Butenoic Acid, 2-Ethylhexyl Ester, (2E)- is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure identity, purity, and consistency meet exacting specifications. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical properties is provided with each shipment, ensuring full traceability and compliance for your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials. Due to its nature as an ester that is easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation of quality. Recommended storage temperature is 15-25°C.
