BQC Phenolic Compounds Assay Kit is a quick, easy, and selective assay to quantify phenolic compounds in a wide variety of samples.

BQC Phenolic Compounds Assay Kit is based on the reaction between diazonium salts and phenolic compounds. Under alkaline conditions the diazonium group specifically couples with reactive phenolic hydroxyl groups to form colorimetrically detectable stable azo complexes (λ= 480 nm).

Catechin is used as the reference standard compound for this Phenolic Compounds Assay, and the results are expressed as Catechin Equivalents (CE).
