Description

1-Acetate 4-Methanesulfonate 1,4-Butanediol is a high-purity, functionalized derivative of 1,4-butanediol, serving as a critical bifunctional building block in advanced organic synthesis. This compound matters for its ability to introduce both acetate and mesylate leaving groups, enabling precise and sequential chemical modifications in complex molecule construction. It is primarily needed by research and development chemists and process engineers in the pharmaceutical and fine chemical industries for the synthesis of active pharmaceutical ingredients (APIs), specialty polymers, and complex organic intermediates.

Application

• Pharmaceutical Intermediate: A key precursor in the multi-step synthesis of complex drug molecules and active pharmaceutical ingredients (APIs).
• Polymer Chemistry: Used as a monomer or cross-linking agent for producing specialty polyesters and polyurethanes with tailored properties.
• Organic Synthesis Building Block: Employed in research laboratories for constructing complex organic molecules, leveraging its two distinct reactive sites for sequential functionalization.
• Liquid Crystal & Electronic Materials: Serves as a starting material in the synthesis of advanced materials for display technologies and electronic applications.
• Agrochemical Synthesis: Utilized in the development of novel herbicides, pesticides, and plant growth regulators.
• Bioconjugation & Linker Chemistry: Acts as a heterobifunctional linker for attaching molecules in bioconjugation and probe development.

Quality Control

Our 1-Acetate 4-Methanesulfonate 1,4-Butanediol is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high chemical purity and identity confirmation. Certificates of Analysis (COA) detailing purity, assay, and impurity profiles are available upon request to support your quality assurance and regulatory documentation 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 under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
