Description

Sodium 1-Butanethiolate is the sodium salt of 1-butanethiol, a versatile organosulfur reagent. This compound is a valuable building block in organic synthesis, particularly for introducing the butylthio moiety into target molecules. It is primarily used by research chemists and process development scientists in the pharmaceutical, agrochemical, and specialty chemical industries for applications such as nucleophilic substitution reactions and as a ligand precursor.

Application

• Pharmaceutical Intermediate: Key reagent in the synthesis of active pharmaceutical ingredients (APIs) containing sulfur-based functional groups.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and insecticides where the butylthio group modifies biological activity.
• Ligand and Catalyst Preparation: Serves as a precursor for generating metal-thiolate complexes used in catalysis and materials science.
• Organic Synthesis Building Block: Employed in nucleophilic substitution and addition reactions to construct complex organic molecules.
• Polymer Modification: Can be used to introduce thiolate groups into polymer chains for functional materials.
• Flavor and Fragrance Industry: Potential intermediate in the synthesis of sulfur-containing aroma compounds.

Quality Control

Our Sodium 1-Butanethiolate is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with key parameters including assay (by titration), identification (IR), and impurity profiles. Our quality systems support compliance with cGMP and ISO standards for research and industrial use.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated place. Recommended storage temperature is 2-8°C for long-term stability. Due to its hygroscopic and easily oxidized nature, containers must be kept tightly sealed and allowed to reach room temperature before opening to minimize moisture ingress.
