    Alpha Lipoic Acid CAS 1077-28-7

    Alpha Lipoic Acid is a sulfur‑containing organic compound supplied as a chemical raw material and intermediate, also commonly referred to as α‑lipoic acid, thioctic acid, or 1,2‑dithiolane‑3‑pentanoic acid in technical and regulatory documentation. Identified by CAS 1077‑28‑7, it features a cyclic disulfide structure that participates in redox reactions and serves as a functional building block in formulated industrial systems. The material is typically applied as an antioxidant intermediate in regulated manufacturing processes where defined purity and molecular consistency are required. From a supply perspective, it is provided with competitive factory pricing, customized specifications, and complete documentation including MSDS, TDS, COA, suitable for regulated bulk supply for industrial use.

    FAQ - Technical & Supply Chain

    • Q:

      Is alpha lipoic acid supplied as an industrial raw material rather than a finished formulation?

      A: Yes. It is typically supplied as a raw material or intermediate intended for further industrial processing or formulation.
    • Q:

      Does USP/EP grade refer to a different CAS number?

      A: No. USP and EP grades describe specification standards, while the chemical identity and CAS number remain the same.
