Each vial contains 10 mg of TB-500, a synthetic fragment of thymosin beta-4, supplied as a lyophilized powder. Purity is ≥99% by HPLC, with identity confirmed by mass spectrometry, and a lot-specific certificate of analysis is available for download. The compound is sold for research use only.
Why the ≥99% HPLC figure and the CAS number matter
- Purity with its method: The figure is ≥99% by HPLC, not a generic grade claim. A purchasing officer can compare that number against a specification sheet directly.
- Identity confirmation: Mass spectrometry confirms identity alongside the HPLC purity figure. Two methods, two lines on the certificate.
- Documented identifiers: Molecular formula C38H68N10O14, molecular weight 889.0 g/mol, CAS 77591-33-4. These allow the material to be logged in an inventory system without guesswork.
- Certificate per lot: The certificate of analysis is lot-specific and downloadable, so records match the vial actually received.
- Quantity stated per vial: Net content is 10 mg per vial. This item is supplied as a single vial.

Who the 10 mg TB-500 vial suits
The 10 mg vial fits an in-vitro laboratory that works through a single compound over several experiments and wants one lot number covering all of them. It also fits a purchasing officer who must file identity and purity documentation before the material enters a reagent inventory, since the certificate of analysis names the lot, the ≥99% HPLC purity and the mass spectrometry confirmation. Ordering is limited to laboratories and qualified researchers. Store the sealed vial at -20 °C, protected from light and moisture, and retain the lot-specific certificate with the sample record. For laboratory research use only. Not for human or veterinary use.
Common questions
Does the certificate of analysis match the vial I receive?
Yes. The certificate of analysis is lot-specific and available for download, stating purity of ≥99% by HPLC and identity confirmed by mass spectrometry.
How should the vial be stored once it arrives?
The lyophilized powder should be stored sealed at -20 °C, protected from light and moisture.
How is the order shipped, and who may order it?
Orders ship from Richmond, BC at ambient temperature in an insulated mailer with desiccant, and the material is sold to laboratories and qualified researchers for research use only.
