Description

1-Carboxy-1-Methylethoxyammonium Chloride is a versatile quaternary ammonium compound with a reactive carboxylate group. This bifunctional structure makes it a valuable intermediate for synthesizing specialty chemicals and functional materials. It is particularly sought after by manufacturers in the pharmaceutical, agrochemical, and polymer industries for its utility in creating betaine-type surfactants, phase-transfer catalysts, and advanced monomers.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds requiring quaternary ammonium or betaine functionalities.
• Surfactant & Detergent Precursor: Serves as a key building block for producing amphoteric and betaine-based surfactants with excellent foaming and mildness properties.
• Polymer & Resin Modification: Acts as a monomer or cross-linking agent for creating specialty polymers with enhanced solubility, adhesion, or ionic characteristics.
• Agrochemical Synthesis: Employed in the production of herbicides, fungicides, and plant growth regulators that benefit from its ionic and reactive properties.
• Phase-Transfer Catalyst (PTC): Functions as an effective catalyst in organic synthesis reactions between reagents in immiscible phases.
• Personal Care Ingredients: A precursor for mild, skin-friendly conditioning agents and emulsifiers in cosmetics and toiletries.
• Corrosion Inhibitor Formulation: Used in developing additives for industrial water treatment and metalworking fluids.
• Research & Development: A valuable reagent for academic and industrial R&D in organic and medicinal chemistry.

Quality Control

Our 1-Carboxy-1-Methylethoxyammonium Chloride is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise specifications for industrial and research applications. Certificates of Analysis (COA) documenting batch-specific results are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed and under dry conditions to prevent product degradation. Keep away from incompatible materials.
