Di-tert-butyl dicarbonate
Based on 1 Customer Validation
Di-tert-butyl dicarbonate (tBOC) is a covalent modification agent for hydroxyl groups (-OH) on the chitosan molecular chain. Di-tert-butyl dicarbonate selectively modifies chitosan and stabilizes the material structure through hydrophobic encapsulation. Di-tert-butyl dicarbonate reacts with the -OH groups of chitosan to form a hydrophobic layer, and in conjunction with triethylamine (TEA), removes trifluoroacetic acid (TFA) salts produced during the electrospinning process, preserving the nanofiber structure and high porosity of the membrane, and improving the material's cytocompatibility and mineralization-promoting ability. Di-tert-butyl dicarbonate can be used in research in the field of guided bone regeneration (GBR).

Biological Activity
Although electrospun chitosan membranes (ESCMs) possess potential for guided bone regeneration (GBR) due to their biocompatibility, biodegradability, and nanofiber structure (mimicking the natural extracellular matrix ECM), they suffer from the following drawbacks: a) structural instability due to solvent residue, b) excessive surface hydrophilicity, and c) poor cell adhesion. Di-tert-butyl dicarbonate (tBOC) can be combined with TEA to form a "two-step treatment system" to first address the structural stability problem of ESCMs and then optimize their surface properties. The modification process is as follows:
TEA pretreatment: removes TFA salt while preserving the nanofiber structure;
tBOC covalent modification: constructs a hydrophobic protective layer, stabilizing the structure and regulating surface hydrophilicity, thereby enhancing cell-membrane interaction.
Di-tert-butyl dicarbonate-modified electrospun chitosan membranes can increase the adhesion rate of fibroblasts and osteoblasts by 30-50%[1].

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: ≥ 5 mg/mL (22.91 mM); Clear solution
This protocol yields a clear solution of ≥ 5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (50.0 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: ≥ 5 mg/mL (22.91 mM); Clear solution
This protocol yields a clear solution of ≥ 5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (50.0 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.
