Products classified under HTS 2909.50.50.00
Guaiacol USP Grade
Guaiacol is a naturally occurring organic compound classified as an ether-phenol with the formula C6H4(OH)OCH3, used primarily as an expectorant in pharmaceuticals and as an intermediate in chemical synthesis. It falls under HTS 2909.50.5000 as a chemically defined ether-phenol derivative. This product is supplied as a clear liquid with added stabilizers for safe transport.
1-Ethoxy-2,3-propanediol
1-Ethoxy-2,3-propanediol is an ether-alcohol-phenol derivative used as a reactive diluent in polyurethane coatings and epoxy resins. Though primarily ether-alcohol, its phenolic substitution qualifies it under the ether-phenol/ether-alcohol-phenol heading 2909. Supplied as viscous liquid with transport stabilizers.
Vanillyl Ethyl Ether
Vanillyl ethyl ether is a synthetic ether-phenol used in perfumery and flavorings to impart spicy vanilla notes. This chemically defined compound features both phenolic hydroxyl and ether linkage characteristic of heading 2909.50. It is imported as pale yellow liquid for fragrance compounding.
4-Methoxyphenol (Methylcatechol)
4-Methoxyphenol, also known as methylcatechol, is an ether-phenol used as a polymerization inhibitor in acrylic resins and UV stabilizers. This chemically defined compound matches the ether-phenol criteria of heading 2909. It is typically imported as a white crystalline powder with anti-caking agents for handling.
2-Phenoxyethanol Technical Grade
2-Phenoxyethanol is a widely used ether-alcohol-phenol serving as preservative in cosmetics, vaccines, and pharmaceuticals. Its structure (C6H5OCH2CH2OH) qualifies as ether-phenol derivative under HTS 2909.50.5000. Imported as colorless liquid with purity ≥99% and stabilizer package.
