Frequently asked
Eligibility
Who is eligible to purchase?
Qualified researchers, laboratories, universities, and commercial research entities purchasing for in vitro laboratory research. You must be at least 21 and satisfy the conditions in our Research Use Policy. We may ask for documentation of institutional affiliation before fulfilling an order.
What does Research Use Only mean here?
It means the material is supplied for in vitro laboratory research and nothing else. It is not for human or veterinary use, not for diagnostic procedures, and not for use in food, cosmetics, or supplements. This is a condition of sale, not a formality.
Can I order on a purchase order or institutional account?
Yes. Institutional purchase orders and invoiced accounts are welcome. Contact us with the details for your institution and we will set this up.
Documentation
Do you provide certificates of analysis?
Yes, for every lot. Each certificate names the lot, the independent laboratory, the analytical method, the date of analysis, and the result. You can retrieve any certificate from the lot register using the number on the vial.
How is purity determined?
By reverse phase HPLC with UV detection, performed by a third party analytical laboratory. Identity is separately confirmed by mass spectrometry against the expected molecular weight. We publish the figure the laboratory reports.
Why do your product pages not describe what compounds do?
Because a certificate of analysis can establish what a material is, not what it does. We publish analytical identity and purity, and we leave the scientific literature to speak for itself. Any supplier making activity claims about a research material is telling you something its testing cannot support.
Orders and delivery
How should materials be stored?
Storage conditions are listed on each product specification. Materials are supplied lyophilised unless stated otherwise and should be moved to their specified conditions promptly on receipt. We do not publish preparation or handling protocols beyond storage and solubility.
What if a material does not match its certificate?
Tell us within 14 days of delivery with the lot number and your supporting analytical data. We will replace it or refund it. See Returns for the full process.
Do you ship internationally?
We ship within the United States. We do not ship where supply would be unlawful, and where an order cannot lawfully be fulfilled we refund it in full.
