Certificates of Analysis & quality.

Every lot supplied by Catalyst Research Labs is released with a Certificate of Analysis (COA). The COA documents the identity and tested attributes of that specific lot. Materials are supplied for laboratory research use only.

What a Certificate of Analysis includes

Each COA states the product name and catalog number, the lot number, the batch release date and retest date, the net quantity, the analytical methods applied, and the measured results against the lot specification. Where applicable, the certificate references the analytical method used to establish purity and identity.

Analytical methods

Identity and purity are assessed using methods appropriate to the material, which may include high-performance liquid chromatography (HPLC) and mass spectrometry. Reported values describe the analyzed lot only; specifications are stated per lot and may vary between lots.

Lot verification

Each vial carries a lot number and QR code. Enter the lot number on the Verify a lot page, or scan the code, to confirm the lot record and retrieve the original Certificate of Analysis.

Storage & handling

Storage conditions are stated on each label and COA. Standard items are stored at or below 25°C, protected from light; items marked for cold chain are stored at 2–8°C. The purchaser is responsible for maintaining the stated conditions after delivery.

Record retention

Lot records — batch genealogy, release and retest dates, and certificates — are retained and remain verifiable online for the life of the material. A copy of a COA can be requested at any time through the contact details on this site.

Requesting documentation

Qualified buyers can request a current COA, specification sheet, or safety data for any catalog item before placing a request. Documentation is provided for the lot offered at the time of quote.
