Pyrogallol dosage

The pyrogallol assay allows for the identification and quantification of this reducing phenolic compound found in certain plants, cosmetic formulations, chemicals, and materials.
Pyrogallol (1,2,3-trihydroxybenzene) is known for its antioxidant and reducing, but also for its potential toxicity at high concentrations. Therefore, it is essential to monitor its content to ensure the safety, regulatory compliance , and quality of finished products.

Analytical methods

methods chromatographic and spectrophotometric high-precision

• HPLC-DAD (high-performance liquid chromatography) : allows the separation and quantification of pyrogallol even in complex matrices (plants, extracts, cosmetics).
• UV-Vis spectrophotometry : suitable for rapid routine monitoring, particularly in quality control or formulation testing.

recommendations ISO, European Pharmacopoeia or internal methods validated within the framework of an ISO 17025.

Industrial applications

Pyrogallol dosage is essential for:

• of Quality control plant extracts rich in polyphenols,
• Theevaluation of the purity of chemicals and reagents,
• Monitoring oxidative stability in cosmetic formulations,
• of Regulatory verification products containing phenolic agents.

Matrices analyzed

• Plant extracts and plant powders
• Nutraceutical products
• Cosmetic formulations (antioxidant treatments, hair dyes)
• Chemical reagents and technical solvents
• Environmental samples (water, production residues)

Further analyses recommended

For a complete characterization of phenolic compounds, YesWeLab recommends:

• Catechol assay : another reducing dihydroxyphenol similar to pyrogallol,
• Resorcinol assay : monitoring of phenols used in cosmetics and dyes,
• Gallic acid assay : a reference marker for plant tannins and polyphenols.
• Total flavonoid dosage : overall assessment of the antioxidant potential of the extracts.
