Description

3-[(2-Aminoethyl)Dithio]Propionic Acid is a specialized organic compound featuring a unique dithio linkage and both amino and carboxylic acid functional groups. This bifunctional structure makes it a valuable intermediate for creating cleavable cross-links and functionalized polymers in advanced material science. It is primarily sought by researchers and manufacturers in the pharmaceutical, bioconjugation, and polymer chemistry sectors for developing drug delivery systems, smart materials, and biochemical probes.

Application

• Bioconjugation Reagent: Used for creating reversible or cleavable linkages between proteins, peptides, and other biomolecules, crucial for drug delivery and diagnostic assay development.
• Pharmaceutical Intermediate: Serves as a key building block in the synthesis of prodrugs and therapeutic agents that require controlled release mechanisms.
• Polymer Modification: Employed to introduce disulfide bonds into polymer backbones or side chains, enabling the production of stimuli-responsive (e.g., redox-sensitive) hydrogels and nanomaterials.
• Cross-linking Agent: Functions as a cleavable cross-linker for modifying surfaces, encapsulating active ingredients, or creating degradable networks in material science.
• Research Chemical: Utilized in academic and industrial R&D for studying thiol-disulfide exchange reactions and developing novel biochemical tools.

Quality Control

Our 3-[(2-Aminoethyl)Dithio]Propionic Acid is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for research and synthesis applications. A Certificate of Analysis (COA) detailing specific results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
