Pentaethylene glycol di-p-toluenesulfonate, 90+%

Description

CAS: 41024-91-3 | C24H34O10S2 | 546.646 g/mol

Pentaethylene glycol di-p-toluenesulfonate is used in the preparation of calix[4]arenes, calix[5]arenes, and crown ethers. It is also used in the preparation of 3?-formylbenzo-18-crown-6 by undergoing coupling reaction with 2,3-dihydroxybenzaldehyde.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Applications
Pentaethylene glycol di-p-toluenesulfonate is used in the preparation of calix[4]arenes, calix[5]arenes, and crown ethers. It is also used in the preparation of 3′-formylbenzo-18-crown-6 by undergoing coupling reaction with 2,3-dihydroxybenzaldehyde.

Solubility
Not miscible or difficult to mix in water.

Notes
Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage. It is hygroscopic in nature.
