Pyrogallol, 98+%

Description

CAS: 87-66-1 | C6H6O3 | 126.11 g/mol

Pyrogallol is used in hair dying and suturing materials dying. It is used as a developing agent in black and white developers, as a metal-complexing agent and is involved in oxygen absorption in gas analysis. It exhibits antiseptic properties. Its alkaline solution is used to absorb oxygen from air, thereby it plays a vital role to calculate the amount of oxygen in air.

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.
