Built for Serious Research
High-Purity Standards
Every Sirius Molecules compound is manufactured to strict purity benchmarks and tested for identity and composition prior to distribution. Our quality standards ensure every shipment meets the integrity your research demands.
Third-Party Tested
Every batch is independently verified by an external 3rd party analytical laboratory using HPLC and mass spectrometry. Independent validation is essential to the quality control that allows us to stand behind every product.
Batch-Level Traceability
Every compound batch is tied to a specific lot number, fully documented from sourcing through fulfillment. A batch-specific Certificate of Analysis (CoA) is accessible for every order so your research is reproducible and audit-ready.
Secure & Reliable Supply
Consistent sourcing and dependable fulfillment you can trust. Inventory is held in cold temperature-controlled storage. Products are fullfilled from our US-based cGMP facility using professional handling, same-day order processing, and cold-chain Air delivery.
