About Keystone Aminos
Research-grade compounds. Verified purity. US-domestic shipping.
Our Mission
Keystone Aminos exists to supply qualified laboratories and research professionals with reliable, verified-purity research compounds. Our focus is simple: consistent quality, transparent documentation, and dependable fulfillment — so researchers can spend their time on the science, not on second-guessing their materials.
Quality & Testing
- Every batch is submitted for independent third-party analysis, including HPLC (high-performance liquid chromatography) and mass spectrometry.
- A Certificate of Analysis (COA) is available for each batch, documenting identity and purity results.
- Our purity standard for catalog compounds is ≥99% unless otherwise stated on the product page.
- Products are handled and stored under conditions appropriate for laboratory reference materials.
Fulfillment
We ship exclusively within the United States (domestic only) — including US territories. Orders ship with tracked service for a flat $10 fee, and shipping is free on orders over $300. Tracking information is emailed as soon as your order leaves our facility.
