How Each Lot Is Tested

Independent release analysis. Every batch runs through reverse-phase HPLC with UV detection at 214 nm, followed by ESI-MS in positive mode for molecular identity, before it is listed. Elemental impurity screening follows ICH Q3D guidance where applicable.

Lot records are retained online and can be pulled by compound name on the batch record page. Full method packages are available on request for institutional and KYC-verified buyers.
