| Identity (MS) | ESI-TOF Mass Spectrometry | Exact Molecular Weight ± 0.5 Da | Conforms |
| Residual Solvents | Headspace GC-MS | USP <467> Guidelines | < 0.1% w/w |
| Counter-ion Content | Ion-Exchange Chromatography | Trifluoroacetate / Acetate | Quantified per lot |
All reference products are strictly intended for scientific laboratory research and in-vitro analytical testing.
Quality Assurance & Storage Guidelines
Reference materials must be kept under controlled desiccated conditions at -20°C. Upon reconstitution in analytical grade sterile solvents, stock solutions should be aliquoted to avoid freeze-thaw cycles.
