Products classified under HTS 2922.29.81.90
4-Aminophenol
4-Aminophenol is a chemically defined organic compound featuring both amino (-NH2) and hydroxy (-OH) groups attached to a benzene ring, classifying it as an oxygen-function amino-compound under heading 2922. It contains only one type of oxygen function (phenol) and no additional oxygen groups. Commonly used as an intermediate in pharmaceutical and dye production.
2-Aminophenol (o-Aminophenol)
2-Aminophenol is an amino-phenol with ortho-positioned amino and hydroxy groups on benzene, fitting HTS 2922.29 as an oxygen-function amino-compound with single oxygen function. Used primarily as a dye intermediate and in rubber antioxidants. Its structure excludes it from multi-oxygen function categories.
Metanilic Acid (3-Aminobenzenesulfonic Acid)
Though containing sulfonic acid, metanilic acid classifies here as an amino-phenol derivative not qualifying as sulfonated under exclusion notes, with primary oxygen amino-function. It's a key intermediate for azo dyes. Falls under 'other' amino-phenols per hierarchy.
p-Aminosalicylic Acid (PAS)
p-Aminosalicylic acid features amino and single phenolic hydroxy with additional carboxylic acid, but classifies as oxygen-function amino-compound under 2922.29 'other'. Used as anti-tuberculosis pharmaceutical intermediate. Single phenolic oxygen function distinguishes it.
2-Amino-4-chlorophenol
This halogenated amino-phenol contains chloro substituent but retains single oxygen function classification under 2922.29 per notes on halogenated derivatives. Used in pesticide and dye synthesis. 'Other' category captures such substituted phenols.
N-(4-Aminophenyl)acetamide (p-Aminoacetanilide)
p-Aminoacetanilide is an N-acetylated amino-phenol ether equivalent, with single oxygen function in acetamido group classifying under 2922.29.81.90. Intermediate for paracetamol and dyes. Acetyl doesn't constitute additional oxygen function.
