Guaiacol - 98%, high purity , CAS No.90-05-1
Basic Description Synonyms guaiacol|2-Methoxyphenol|90-05-1|o-Methoxyphenol|2-Hydroxyanisole|Guaiastil|Pyroguaiac acid|o-Guaiacol|o-Hydroxyanisole|Pyrocatechol monomethyl ether|Phenol, 2-methoxy-|1-Hydroxy-2-methoxybenzene|Anastil|Guaicol|Phenol, o-methoxy-|Methylcatechol|Guaicolin Specifications & Purity ≥98% Biochemical and Physiological Mechanisms 愈创木酚和2，4，6-三氯苯甲醚是造成葡萄酒软木污染的原因 Storage Temp Argon charged Shipped In Normal Product Description Guaiacol is a phenolic natural product first isolated from Guaiac resin, as well as the oxidation of lignin. Guaiacol is readily oxidized by the heme iron of peroxidases including the peroxidase of cyclooxygenase (COX) enzymes, hence it serves a reducing co-substrate for COX reactions.1 The color yield per peroxide at 470 nm is 6,650 (M peroxide reduced)-1 cm-1.2,3,4 Two moles of zguaiacol are oxidized for each mole of hydroperoxide reduced by the peroxidase. The resulting guaiacol chromophore can be used for the colorimetric determination of hydroperoxidase activity.
