Description

3-(2-Ethoxyethoxy)Propionic Acid is a versatile organic acid ester with a unique ether and carboxylic acid functional group structure. This bifunctional nature makes it a valuable intermediate for synthesizing specialty polymers, surfactants, and fine chemicals where controlled hydrophilicity and reactivity are required. It is particularly sought after by manufacturers in the polymer, agrochemical, and personal care industries for its utility as a building block and modifier.

Application

• Polymer Modification: Used as a reactive monomer or chain transfer agent in the synthesis of acrylic and vinyl polymers to impart flexibility and specific solubility profiles.
• Surfactant & Emulsifier Synthesis: Serves as a key intermediate for producing non-ionic surfactants with tailored hydrophilic-lipophilic balance (HLB) for agrochemicals and industrial cleaners.
• Pharmaceutical Intermediates: Employed in the synthesis of active pharmaceutical ingredients (APIs) and prodrugs requiring ether-linked carboxylic acid functionalities.
• Coating & Resin Additives: Acts as a viscosity modifier and cross-linking agent in specialty coatings, inks, and adhesive formulations.
• Lubricant & Fuel Additives: Utilized in the production of ester-based additives that improve lubricity and stability.
• Chemical Research & Development: A valuable building block in organic synthesis for creating novel compounds in academic and industrial R&D settings.

Quality Control

Our production of 3-(2-Ethoxyethoxy)Propionic Acid adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including assay, identity confirmation, and impurity profiling, to ensure it meets precise customer specifications and industry standards. A Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong oxidizing agents, bases, and sources of heat. Recommended storage temperature is 15-25°C. The container should be kept tightly sealed when not in use to minimize moisture absorption.
