Products classified under HTS 2922.50.19.00
Guaiacol Carbonate
Guaiacol carbonate is a derivative of guaiacol, featuring a carbonate ester group attached to the phenolic oxygen, classifying it as an aromatic amino-compound with oxygen function under HTS 2922.50.19.00. It is used in pharmaceutical synthesis as an intermediate for expectorant drugs and cough syrups.
Guaifenesin USP
Guaifenesin, or 3-(2-methoxyphenoxy)-1,2-propanediol, is a guaiacol derivative serving as an expectorant in cough medications, falling under HTS 2922.50.19.00 as an aromatic amino-compound with oxygen function. It meets 'drugs: other' criteria due to its pharmaceutical application.
Guethol
Guethol, chemically 2-methoxy-4-(1-propenyl)phenol, is a guaiacol derivative used as a flavoring agent and topical antiseptic, classified under HTS 2922.50.19.00 for its aromatic structure with oxygen and phenolic functions. It qualifies as a 'drug' derivative in pharmaceutical contexts.
Veratrylguaiacol
Veratrylguaiacol is a dimeric guaiacol derivative used in organic synthesis and as a biochemical research tool, falling under HTS 2922.50.19.00 due to its aromatic amino-phenol structure with oxygen functions. It serves as an intermediate in drug development.
Guaiacol Glycerol Ether
Guaiacol glycerol ether is an ether derivative linking guaiacol to glycerol, used in expectorant formulations and classified under HTS 2922.50.19.00 as a guaiacol-based aromatic compound with oxygen function. It aligns with 'drugs: other' for medicinal intermediates.
4-Nitroguaicol Sodium
4-Nitroguaicol sodium salt is a nitro-derivative of guaiacol used in dye intermediates and pharmaceuticals, classified under HTS 2922.50.19.00 as it retains guaiacol's aromatic oxygen-amino structure. Nitro groups are included per chapter notes for such derivatives.
Guaiacyl Acetate
Guaiacyl acetate is an ester derivative of guaiacol used in fragrance and pharmaceutical synthesis, falling under HTS 2922.50.19.00 per rules for esters classified with the later-heading parent compound. Its aromatic oxygen function qualifies it as a drug intermediate.
Methoxsalen (8-Methoxypsoralen)
Methoxsalen, a furocoumarin derivative related to guaiacol structures, is used in PUVA therapy for psoriasis and classifies under HTS 2922.50.19.00 as an aromatic oxygen-function compound with drug application. Its phenolic methoxy group aligns with guaiacol derivatives.
Guaiacol Phosphate
Guaiacol phosphate is a phosphorylated derivative used in antitussive formulations, classified under HTS 2922.50.19.00 for its guaiacol base with oxygen function. It fits 'drugs: other' as a pharmaceutical intermediate.
Creosol (4-Methylguaiacol)
Creosol, or 2-methoxy-4-methylphenol, is a guaiacol derivative from wood creosote used as a disinfectant and flavorant, under HTS 2922.50.19.00 as an aromatic oxygen-function compound. It qualifies via phenolic structure and drug-like applications.
