PEGs
Not applicable. This compound is a chemical linker used for synthesis. The alkyne group targets azides for click chemistry, and the acetyl group can be a protecting group or a handle for further modification (e.g., deprotection to an alcohol). |
|---|---|
| ln Vitro |
One ligand is for an E3 ubiquitin ligase, and the other is for the target protein; these two ligands are joined by a linker to form PROTACs. The intracellular ubiquitin-proteasome system is utilized by PROTACs to specifically destroy target proteins[1].
Not applicable. As a chemical reagent, it has no biological activity. Its purpose is to introduce a clickable alkyne handle into another molecule via the acetyl group, or to be deprotected and further functionalized. |
| ln Vivo |
No in vivo activity.
|
| Enzyme Assay |
Not applicable. This is a synthetic building block, not a molecule used in biological assays.
|
| ADME/Pharmacokinetics |
Molecular weight is approximately 126.15 g/mol. This is a very short linker, providing the minimal distance between conjugated molecules. It is typically stored at -20degC or 4degC in a sealed, dry container to prevent hydrolysis of the acetyl group.
|
| Toxicity/Toxicokinetics |
No toxicity data available. Standard safety precautions for organic solvents and alkylating agents (alkynes) should be followed. Based on its structure, it is not expected to be highly toxic, but ingestion and skin contact should be avoided.

| Additional Infomation |
This is a fine chemical for research in organic synthesis and chemical biology. Its small size and simplicity make it useful for introducing an alkyne tag with minimal impact on the parent molecule's properties. The acetyl group can serve as a protecting group for an alcohol, allowing for two-step conjugation strategies.

Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.
Injection Formulations
Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).

Injection Formulation 4: DMSO : 20% SBE-β-CD in saline = 10 : 90 [i.e. 100 μL DMSO → 900 μL (20% SBE-β-CD in saline)] Oral Formulations
Oral Formulation 1: Suspend in 0.5% CMC Na (carboxymethylcellulose sodium) Oral Formulation 2: Suspend in 0.5% Carboxymethyl cellulose Example: Take the Oral Formulation 1 (Suspend in 0.5% CMC Na) as an example, if 100 mL of 2.5 mg/mL working solution is to be prepared, you can first prepare 0.5% CMC Na solution by measuring 0.5 g CMC Na and dissolve it in 100 mL ddH2O to obtain a clear solution; then add 250 mg of the product to 100 mL 0.5% CMC Na solution, to make the suspension solution (2.5 mg/mL, ready for use in animals).

Oral Formulation 3: Dissolved in PEG400 (Please use freshly prepared in vivo formulations for optimal results.) |
| Preparing Stock Solutions | 1 mg | 5 mg | 10 mg | |
| 1 mM | 6.3231 mL | 31.6156 mL | 63.2311 mL | |
| 5 mM | 1.2646 mL | 6.3231 mL | 12.6462 mL | |
| 10 mM | 0.6323 mL | 3.1616 mL | 6.3231 mL |
*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
