Have tested several batches by NMR — clean spectra, no detectable solvent residues.

Stability data provided on request. Researchers in our group switched to this vendor after the first order.

Pricing is fair for the purity level. Documentation is thorough and the COA is signed and dated.

Reconstituted cleanly in BAC water with zero turbidity. Mass spec confirmed expected molecular weight.

Shipping was fast and the cold-chain held perfectly. Vials sealed properly, no signs of degradation.

Pricing is fair for the purity level. Documentation is thorough and the COA is signed and dated.

Third order from this vendor. Batch-to-batch consistency has been excellent and lyophilization quality is top tier.
