California-Based Supplier

Rare natural product standards made by a California lab.

Sylverity manufactures and characterizes scarce natural product reference standards in California. For U.S. discovery labs, that means direct communication with the lab, simpler domestic logistics, and a supplier who is also the manufacturer.

Why domestic manufacturing matters

When a compound is rare, communication often matters as much as the listing. Working with a domestic manufacturer can simplify questions about identity, availability, documentation, timing, and shipment coordination.

  • Direct communication with the laboratory team
  • Domestic fulfillment for eligible U.S. orders
  • COA and SDS support tied to product records
  • Clear paths for stocked and made-to-order materials

Supplier and manufacturer in one

Sylverity is not a marketplace layer between researchers and anonymous stock. The public catalog reflects compounds made, purified, and characterized through our own laboratory work.

That manufacturer relationship is especially useful for scarce natural products, where a researcher may need confirmation on identity, quantity, documentation, or future availability before committing a project timeline.

Ordering from the catalog

Eligible stocked standards can be purchased directly through checkout. For non-stock compounds, larger quantities, custom targets, or documentation questions, the inquiry path connects the request to the lab for review and follow-up.

Ordering

Order stocked standards directly or ask our lab about custom needs.

Eligible in-stock standards can be purchased through checkout from their product pages. For made-to-order compounds, larger quantities, documentation questions, or custom targets, send an inquiry and our team will confirm feasibility, timing, and next steps.
