Every price shows its cost per milligram so vial sizes can be compared directly. Anything not held on hand is sourced to order and in hand within two days — nothing here is unavailable.

How to compare research materials before ordering

Start with the compound and vial size required for your laboratory work. Open the material page to compare its identity information, price per milligram and available strengths. A smaller vial and a larger vial have separate prices and lot records.

  • Check assay status. A published result applies to the named lot. An assay-pending listing has no qualifying result to rely on yet.
  • Match the document. Request the original laboratory report and compare its sample and lot identifiers with the product record. Our COA reading guide explains the checks.
  • Check fulfillment. On-hand material and material sourced to order have different handling windows. The product page identifies which applies.
  • Compare the full order cost. US shipping is $20 per shipped order. See shipping and returns before ordering.

For identity data and cited literature, use the compound reference. Materials are supplied for laboratory research only.
