Description
Pyrogallol is sensitive to air and light and may become grayish or darker after exposure. Laboratories handling this material therefore need a clearly defined assay specification, controlled impurity limits, and appropriate storage guidance when selecting and using the reagent.
PC6880 is reagent-grade pyrogallol, also known as 1,2,3-trihydroxybenzene, with an assay specification of ≥99.8%. Its product specification defines limits for residue after ignition, chloride, sulfate, iron, and heavy metals as lead.
This laboratory research reagent should be kept in a tightly closed container in a cool, dry, well-ventilated area. Protect the material from light and minimize unnecessary exposure to air. Review the Safety Data Sheet before handling.

Handling and Storage
Pyrogallol absorbs oxygen from the air and may darken after exposure. The product documentation also identifies the material as light sensitive.
Store PC6880 at room temperature in a tightly closed container in a cool, dry, well-ventilated area. Protect it from light, minimize exposure to air, and keep it away from incompatible materials.
- Minimize dust generation and accumulation.
- Use only with adequate ventilation.
- Avoid contact with eyes, skin, and clothing.
- Wear appropriate protective gloves, protective clothing, and eye protection.
- Review the complete SDS before handling, storage, spill response, or disposal.
Signal Word: Danger.
