Amines are organic compounds; nitrogen containing the amino function, a function that is derived from ammonia, by replacing one or two atoms or three atoms of hydrogen, hard, or two or three chunks of alkyl or eryl (R) (methyl, ethyl, phenyl ... Etc.) respectively.
If one atom of ammonia is replaced, obtain a first amino acid (R.NH2)
If two hydrogen atoms were replaced, a secondary amine (R-NH-R)
If three hydrogen atoms are replaced, I get a tertiary amine
Nitrozamines that can react chemically similar to quinine amin oxymate are retained in this item.
Salts (eg nitrate salts, estates, jackets) and amine derivatives (halogenated, salted, nitrated, nitrated, etc.) are also included in this item. However, substituting derivatives containing oxygen functions are in heading 29.05 to 29.20 and their salts are classified in heading 29.22.
The item also does not include derivatives containing one or more hydrogen atoms that have amine functions if substituted with one or more halogens or sulfos (SO3H), nitro (NO2), nitrozo (NOO) or other union methods.
Amines that can become diazotisable and their salts of this heading are also included in this heading even if they are diluted to standard concentrations of the production of iso dyes.
