Thymalin is supplied as a catalogued research material in 10 mg.
Thymalin is not safely described as one peptide. The historical material is a heterogeneous low-molecular-weight peptide extract from calf thymus, while modern market products may use synthetic mixtures or misidentified discrete peptides. A single formula, mass, CAS or PubChem CID would therefore be misleading without a master specification and matching batch fingerprint [1–3].
Chemical properties and registry information
| Property | Value |
|---|---|
| Name and synonyms | Thymus extract, Polypeptides from thymus |
| Material category | Immunomodulator |
| CAS Registry Number | 91080-07-8 |
| Structural features | Polypeptide complex extracted from the thymus gland. |
| Appearance | White to off-white lyophilised powder |
| Solubility | Reconstitute with sterile water or 0.9% NaCl solution. |
| Physical form | Catalogue vial; exact salt/counter-ion and excipients are batch-specific and must be verified in the CoA and SDS. |
Registry values apply only to the specific molecular entity, sequence, termini and material form. Batch records take precedence over family-level literature identifiers.
Thymalin is a proprietary name for a preparation of polypeptides extracted from the thymus gland of calves. It is not a single molecular entity but a mixture of various peptides with molecular weights typically ranging from 1 to 10 kDa.
Research background and published evidence
Published research
Until composition is resolved, the defensible work is chromatographic, mass-spectrometric and peptide-fraction profiling, source-material authentication and batch-to-batch comparability. Biological assay interpretation requires a compositionally comparable and fully documented material [1–3].
Current scientific understanding
Studies of a historical animal extract, individual short peptides or another synthetic mixture cannot be transferred to an unspecified catalogue material. No single-molecule mechanism or outcome claim is supportable until the batch composition is established.
Technical comparison
| Aspect | This catalogue material | Comparator |
|---|---|---|
| Identity | Thymalin: heterogeneous or proprietary thymic peptide material | Thymosin alpha-1: a discrete N-acetylated 28-residue peptide |
| Structural distinction | Mixture identity depends on source and manufacturing process | One defined primary sequence and molecular entity |
| Analytical implication | Requires mixture fingerprint, component distribution and source/process controls | Can be characterized by sequence-specific intact mass and purity methods |
Quality and testing
Quality information is batch- and presentation-specific. Use only the report linked to the exact size and lot. A report listed for another size, lot or similarly named material must not be treated as evidence for this product.
Chromatographic area purity, identity, net peptide or analyte content, water or counter-ion content, sterility, endotoxin and elemental impurities are different measurements. One result does not establish the others. Only tests supported by a visible, matching report should be regarded as available.
Laboratory handling and storage
Store and handle only under the conditions stated on the product label, batch CoA and SDS. Keep the container secured, correctly identified and protected from contamination. Do not infer storage, solvent compatibility or stability from a related compound.
Laboratory preparation, analytical-method selection, risk assessment, personal protective equipment and waste disposal should follow the applicable SDS and the institution's approved procedures.
Regulatory and legal status
| Research-use notice | This material is supplied exclusively for laboratory research by qualified professionals and is not intended for human or veterinary use. Purchasers are responsible for compliance with applicable local requirements. |

Frequently Asked Questions
Do the CAS number and PubChem CID apply to every batch form?
Only when the exact sequence or structure, termini, conjugation, salt or counter-ion and hydration state match. The batch CoA and SDS govern; a related-compound identifier must not be substituted.
What does an analytical purity result mean?
It is method- and report-specific. For example, an HPLC area percentage is not automatically the same as identity, net content, sterility, endotoxin status or absence of elemental impurities.
How should the material be stored and handled?
Follow the exact label, batch CoA and SDS together with the institution's risk assessment. Use only storage and stability information linked to the exact material form and batch.
