Why the ≥99% HPLC figure and the lot certificate matter
Purity paired with method
The figure is ≥99% by HPLC, not an unqualified claim. Purchasing officers can record both the figure and the method in their reagent log.
Identity by mass spectrometry
Molecular weight 1025.2 g/mol and molecular formula C50H68N14O10 are confirmed by mass spectrometry. CAS 189691-06-3 identifies the compound in procurement systems.
One certificate per lot
The certificate of analysis is lot-specific and downloadable. Each vial received can be traced back to the document that describes it.
Lyophilized form
The material arrives as a dry powder rather than a solution. Storage conditions are therefore straightforward to meet in a standard −20 °C freezer.
Desiccant in the mailer
Shipping is at ambient temperature with desiccant inside an insulated mailer, which limits moisture exposure in transit.
Who the 10 mg vial suits
The 10 mg format fits a laboratory running a multi-plate in vitro series from a single lot, and it fits a purchasing officer consolidating one reference compound into a documented reagent inventory. It is offered in one quantity only: 10 mg per vial, with no smaller fill. A group needing several independent lots for comparison should order multiple vials and keep each certificate of analysis with its lot number. Ordering is limited to laboratories and qualified researchers. For laboratory research use only. Not for human or veterinary use.
Common questions
Does the PT-141 10 mg vial come with a certificate of analysis?
Yes. Each lot ships with a downloadable lot-specific certificate of analysis stating purity ≥99% by HPLC, with identity confirmed by mass spectrometry.
How should the lyophilized powder be stored?
Store the sealed vial at -20 °C, protected from light and moisture. It ships at ambient temperature with desiccant.
How much PT-141 is in each vial, and what is the identity data?
Each vial contains 10 mg of lyophilized PT-141, a synthetic cyclic heptapeptide melanocortin analogue: molecular formula C50H68N14O10, molecular weight 1025.2 g/mol, CAS 189691-06-3. Sold for research use only. For laboratory research use only. Not for human or veterinary use.
