Description

4-[[2-(Acetylamino)Ethyl]Dithio]-1-Butanesulfinic Acid Sodium Salt is a specialized organosulfur compound featuring a unique dithio linkage and a sulfinic acid sodium salt moiety. This molecular structure makes it a valuable reagent and intermediate in advanced organic synthesis, particularly for the formation of disulfide bonds and as a precursor in the development of functional materials. It is primarily sought by research institutions and industrial laboratories engaged in pharmaceutical development, biochemical research, and the synthesis of novel polymers or surfactants.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of active pharmaceutical ingredients (APIs), especially those containing disulfide bridges or sulfonamide groups.
• Bioconjugation Reagent: Used for the site-specific modification of peptides, proteins, and antibodies, facilitating drug-antibody conjugates (ADCs) and diagnostic probes.
• Polymer Chemistry: Serves as a functional monomer or cross-linking agent for creating polymers with responsive or self-healing properties.
• Chemical Research: A versatile reagent in organic synthesis for constructing complex sulfur-containing heterocycles and as a sulfinylating agent.
• Surface Modification: Used to create self-assembled monolayers (SAMs) on gold or other metal surfaces for sensor and coating applications.

Quality Control

Our production of 4-[[2-(Acetylamino)Ethyl]Dithio]-1-Butanesulfinic Acid Sodium Salt adheres to stringent in-process controls to ensure batch-to-batch consistency and high purity. Each lot is fully characterized and tested against established specifications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place 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.
