5. Product Quality, Testing, and Representations

Cornerstone Research Supply is committed to quality and transparency. All products undergo independent third-party laboratory testing prior to release, including testing for:

• Identity (molecular structure verification)
• Purity analysis
• Potency verification

• Residual solvent testing
• Sterility and microbial contamination
• Endotoxin levels

Certificates of Analysis (COAs) and batch-specific laboratory documentation are made available on our website for customer review. While we maintain rigorous quality standards, we do not warrant that all products are suitable for every specific research application. Customers are responsible for independently evaluating the suitability of products for their intended research purposes.

7. Shipping and Delivery

We ship to addresses within the United States. International shipping availability may vary. Risk of loss and title for products pass to you upon delivery to the carrier. We are not responsible for delays caused by carriers, customs, or circumstances beyond our control.

It is your responsibility to ensure the delivery address is accurate. We are not liable for packages lost or delayed due to incorrect address information provided at checkout.

8. Returns and Refunds
