Formula, molecular weight and PubChem CID retrieved from the PubChem PUG REST API by CAS number. Values describe the compound, not any particular lot — the lot Certificate of Analysis is the reference for the material supplied.

Handling

Supplied as a lyophilized powder. Store the lyophilized material cold and protected from light and moisture, per the storage line on the lot COA. Reconstitute with an appropriate diluent — the reconstitution calculator gives the resulting concentration for a given mass and volume. Solubility varies by compound; the COA is the reference.

Repeated freeze–thaw cycling degrades peptides in solution. See freeze–thaw cycles and peptide degradation and the storage temperature guide.

Why identity data matters

The same compound name can cover more than one molecule — different published sequences, different terminal modifications, different counter-ions. CAS number, molecular formula and mass are what pin the substance down; the name alone does not. That is the practical reason a lot-matched COA is worth reading before the material is used. See one name, several sequences.

Research use only. This page is chemical reference information. The compound is supplied strictly for in-vitro laboratory research, is not for human or animal consumption, and is not intended to diagnose, treat, cure or prevent any disease. You must be 21 or older to purchase.
