Pyrogallol dosage

The analysis of pyrogallol 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

high-precision chromatographic and spectrophotometric methods

• 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.

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

Industrial applications

Pyrogallol dosage is essential for:

• Quality control of plant extracts rich in polyphenols,
• The evaluation of the purity of chemicals and reagents,
• Monitoring oxidative stability in cosmetic formulations,
• Regulatory verification of 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.
