BOP hexafluorophosphate
Based on 1 Customer Validation
BOP hexafluorophosphate is a phosphonium-type condensing agent. BOP hexafluorophosphate activates the carboxylic acid component to form a highly reactive O-benzotriazole ester (active ester) intermediate, which then reacts with the amino component to form an amide bond (peptide bond). BOP hexafluorophosphate is applicable to solid-phase polypeptide synthesis and nucleoside modification.

Activité biologique
The racemization degree of Boc-His (Tos) is minimized when BOP hexafluorophosphate is used with equimolar diisopropylethylamine, and the epimer formation rate reaches approximately 3% upon excessive addition of diisopropylethylamine[1].
BOP hexafluorophosphate activates the amide functional group of silyl-protected pyrimidine nucleosides to generate in situ O4-(benzotriazol-1-yl) derivatives for C4 modification[2].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (5.65 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (5.65 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
