Barbituric Acid
Barbituric acid (malonylurea) is a heterocyclic compound with a pyrimidine ring structure, serving as the core scaffold for barbiturate pharmaceuticals. It is classified under HTS 2933.52.1000 as a separate chemically defined organic compound containing a nitrogen hetero-atom in a pyrimidine ring. Primarily used as an intermediate in synthesizing barbiturate drugs.
Pharmaceutical Grade Barbituric Acid Powder
High-purity barbituric acid powder (≥99%) manufactured specifically for use in API synthesis of barbiturate sedatives and anticonvulsants. Meets USP/EP pharmacopeia standards and is classified under HTS 2933.52.1000 as the pure malonylurea compound. Supplied in bulk for pharmaceutical manufacturing.
5,5-Diethylbarbituric Acid Intermediate
No, this is specifically barbituric acid itself. Let me correct: Pure barbituric acid used as precursor for synthesizing 5,5-diethylbarbituric acid (barbital). Classified under HTS 2933.52.1000 as the unsubstituted malonylurea meeting chapter 29 requirements for separate chemically defined compounds.
Laboratory Reagent Barbituric Acid
ACS reagent grade barbituric acid for analytical chemistry and organic synthesis in research laboratories. Supplied as white crystalline powder with specified purity for qualitative and quantitative analysis. Classifies under HTS 2933.52.1000 as a separate chemically defined heterocyclic compound.
Barbituric Acid Technical Grade
Technical grade malonylurea (90-95% purity) for industrial synthesis of pharmaceutical intermediates and agrochemicals. Less refined than pharmaceutical grade but still qualifies as separate chemically defined compound under HTS 2933.52.1000 chapter notes.
Barbituric Acid with Stabilizer
Barbituric acid containing added stabilizer necessary for preservation during transport, as permitted by Chapter 29 note (f). The stabilizer does not render it suitable for specific use. Remains classified under HTS 2933.52.1000 as the principal chemically defined compound.
