Certificates of Analysis (COAs)

Every batch we offer is independently tested and documented to support consistency, identity, and quality. A batch-specific Certificate of Analysis (COA) provides key analytical information, including available purity and identity testing results, so researchers can review relevant product documentation before conducting laboratory research.

Third-Party Verified

Every COA reflects independent, ISO-certified lab results.

HPLC Purity Analysis

Reverse-phase HPLC confirms purity for every batch.

Identity Verification

LC-MS confirms molecular weight and sequence identity.

Batch Documentation

Lot number, test date, and results are recorded for every batch.

What's Included in a COA

Each Certificate of Analysis provides important batch-specific information designed to give researchers greater transparency into the materials they purchase. While available details may vary by product or testing laboratory, COAs typically include key identification, analytical, and handling information associated with the tested lot.

Lot & Batch Information

Unique lot number, manufacture date, and quantity.

Purity Results

HPLC purity percentage for the tested batch.

Identity Confirmation

Certificate of Analysis FAQs

Find answers to common questions about our Certificates of Analysis, including what information they contain, how to locate your product’s lot number, when documentation is available, and how to request assistance with a specific batch.

What information is included on a COA?

Each Certificate of Analysis includes the lot number, manufacture date, HPLC purity results, LC-MS identity confirmation, and recommended storage and handling conditions.

How do I find the lot number on my product?

The lot number is printed directly on the vial label, typically below the product name and concentration.

Can I get a COA before I purchase?

Yes. A sample Certificate of Analysis is available for any product before you buy — just reach out to our support team and we’ll send one over.

Are COAs issued by an independent lab?

Yes. All purity and identity testing is performed by independent, ISO-certified third-party laboratories, not by us.

What if my lot isn't listed yet?
