Molecular identity

Published structural information for research review—not measured results, a certificate of analysis, or confirmation of a KCC lot’s identity. Match the exact form to released supplier and lot documentation before use.

Thymosin Alpha-1 / Thymalfasin

Parent compound; counterions and hydration excluded

Reference sequence / structural notationAc-SDAAVDTSSEITTKDLKEKKEVVEEAEN-OH
Backbone residues
28
Reference formula
C129H215N33O55
Reference molecular weight
3108.28 g/mol
Reference CAS

N-acetylated 28-residue peptide. Distinct from thymosin β4 and the fragment described as TB-500.

    How to read the notation

    Sequences run from N to C. Ac = acetyl; -NH2 = C-terminal amide; -OH = free C-terminal acid; D- marks stereochemistry; Aib = α-aminoisobutyric acid; Nle = norleucine; pGlu = pyroglutamate; γ-Glu = gamma-glutamyl linkage; AEEA = 2-[2-(2-aminoethoxy)ethoxy]acetic acid. Lipid linkers and ring closures are described separately. Molecular weights are reference molar masses, not measured MS peaks or per-vial amounts.

    STORAGE & HANDLING

    Follow the applicable COA and documentation.

    Storage, handling, physical form, and stability conditions may vary by material and lot. Use only the instructions supplied with the released documentation and your institution’s approved laboratory procedures. Do not rely on third-party clinical or administration protocols.

    What the lab record should establish

    Documentation guide—not a claim that these assays have been performed. Only the approved document for the exact lot can establish results. An absent report means no result is published, not that a test passed.

    Identity & structure
    Mass spectrometry / LC–MS and sequence or structural confirmation, as applicable.
    Purity & content
    Lot-specific chromatogram, method and purity result; net compound content reported separately from chromatographic area percentage.
    Chemical form & impurities
    Counterion, hydration, residual solvents and relevant elemental impurities, where characterized.
    Handling & traceability
    Exact lot, SDS, physical form, storage conditions and supported retest or expiry date. Microbiological or endotoxin results only when applicable and documented.
