Medchemexpress LLC Polyoxyethylene stearyl ether | 9005-00-9 | MFCD00074177 | 99.0% | ≈1,100 g/mol | (C2H4O)nC18H38O | 25 G
Polyoxyethylene (20) stearyl ether is an ethoxylated stearyl alcohol (PEG-20 stearyl ether) nonionic surfactant used as a PEGylated lipid excipient for formulation research. It is commonly employed to form and stabilize nanoparticles and liposomal systems; the material is typically a colorless to off-white oil with CAS 9005-00-9.
- Acts as a nonionic PEGylated lipid surfactant for nanoparticle and liposome formulation.
- Provides steric stabilization and improves colloidal stability.
- Soluble in ethanol at approximately 100 mg/mL with ultrasonic assistance.
- Colorless to off-white oil, suitable for formulation studies.
- Average ethoxylation degree approximately n ≈ 20; number-average molecular weight ~1,100 g/mol.

Medchemexpress LLC Epoy (SD-142) | 245660-13-3 | 98.8% | 323.30 | 5 MG
EpoY (SD-142) is an irreversible inhibitor of the brain's primary tubulin tyrosine carboxypeptidase (TCP), a complex formed by vasohibin-1 (VASH1) and the small vasohibin binding protein (SVBP). It inhibits TCP with an IC50 value of approximately 500 nM, leading to a decrease in detyrosinated alpha-tubulin levels, which is vital for microtubule dynamics and neuronal differentiation. This inhibition results in significant differentiation defects and has been linked to issues associated with cancer and cardiomyopathies.
