5,5-Diethylbarbituric Acid Intermediate
Pure barbituric acid used as an intermediate for synthesizing 5,5-diethylbarbituric acid (barbital). It is a separate chemically defined organic compound with a pyrimidine ring, falling under tariff item 2933.52.00 as malonylurea (barbituric acid) and its salts.
Amobarbital Sodium
Amobarbital sodium is the sodium salt of amobarbital, a long-acting barbituric acid derivative with a pyrimidine ring structure. It is used medically as a sedative or hypnotic. As a salt of malonylurea (barbituric acid), it falls under tariff item 2933.52.00, which covers such compounds with a pyrimidine ring.
Barbituric Acid
Barbituric acid (malonylurea) is a heterocyclic compound with a pyrimidine ring, serving as the core scaffold for barbiturate pharmaceuticals. It is a separate chemically defined organic compound, classifiable under tariff item 2933.52.00.
Barbituric Acid Aqueous Solution
Barbituric acid dissolved in water, as permitted by Chapter 29 note (d). The aqueous solution is a normal method of putting up for safety or transport, and the solvent does not render it suitable for specific use, so it remains classifiable under tariff item 2933.52.00.
