Description

Ethyl 1-Butanesulfonate is a versatile organosulfur compound used as a key alkylating agent and synthetic intermediate. Its primary value lies in its ability to introduce the butanesulfonate functional group into target molecules, enabling the synthesis of specialized surfactants, pharmaceuticals, and performance chemicals. This product is essential for R&D chemists and process engineers in the pharmaceutical, agrochemical, and specialty chemical industries seeking to develop novel sulfonate derivatives or modify compound solubility and ionic properties.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) and prodrugs requiring sulfonate ester functionalities.
• Agrochemical Synthesis: Serves as a building block for creating novel herbicides, fungicides, and plant growth regulators.
• Surfactant & Detergent Manufacturing: A key precursor for producing anionic surfactants with specific chain lengths for industrial and institutional cleaning formulations.
• Polymer Modification: Employed to introduce sulfonate groups into polymers to alter hydrophilicity, ionic character, or adhesion properties.
• Chemical Research & Development: A valuable reagent for organic synthesis, particularly in nucleophilic substitution reactions to create sulfonated analogs.
• Electrolyte Additive: Investigated for use in lithium-ion battery electrolytes to improve stability and performance at high voltages.

Quality Control

Our Ethyl 1-Butanesulfonate is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including assay (HPLC), identification (IR, NMR), and impurity profiling, to ensure it meets the high-purity standards required for synthetic applications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance with your internal specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); keep the container tightly sealed under an inert atmosphere (e.g., nitrogen) to prevent degradation from atmospheric moisture.
