Why the ≥99% HPLC figure is paired with mass spectrometry
Two methods answer two different questions. HPLC gives the purity figure, ≥99% for this lot class, while mass spectrometry confirms that the material matches the stated molecular weight of 5135.9 g/mol and the formula C221H366N72O67S. Both are recorded on the certificate of analysis issued per lot.
For a 44-amino-acid analogue with an N-terminal trans-3-hexenoic acid group, that identity check matters when a purchasing officer has to reconcile a reagent against CAS 218949-48-5 in an inventory record. The lot number on the vial ties the powder back to its own document. The compound is supplied for research use only.
Good to know before you order
- Net content: The vial contains 5 mg of lyophilized powder; the 0.05 kg figure is the packed weight recorded for the courier, not the net content.
- What arrives: One vial of lyophilized tesamorelin, 5 mg, with a downloadable certificate of analysis for its lot. No diluents or consumables are included in this listing.
- Shipping from British Columbia: Orders leave Richmond, BC in an insulated mailer with desiccant, shipping at ambient temperature; on arrival, store sealed at -20 °C away from light and moisture.
Sold to laboratories and qualified researchers only. For laboratory research use only. Not for human or veterinary use.
