Cold-chain packaging arrived within specification; vials were properly sealed and labeled with legible lot numbers. Turnaround from order to receipt was three business days.

Reconstitution was clean with no haze. Mass-spectrometry identity confirmation matched the target reference compound, and lot-to-lot consistency has held across repeat orders.

The certificate of analysis was available prior to purchase and matched the delivered lot on identity and purity. The reference material met our intake QC criteria without exception.

Vials were labeled consistently with the accompanying paperwork and net content was within the stated tolerance. Storage guidance on the certificate matched the product documentation.
