Barbituric acid

Barbituric acid (2,4,6-trihydroxypyrimidine, CAS 67-52-7) from Hebei Hua-chem Group is an off-white crystalline powder with a purity of 99.0% as verified by HPLC analysis. The compound exhibits a sharp melting point of 245°C, indicating consistent crystalline structure and low impurity levels suitable for pharmaceutical intermediate use. This grade targets manufacturers synthesising barbiturate derivatives, where batch-to-batch consistency in melting behaviour directly correlates with downstream reaction yields.

The molecular framework consists of a pyrimidine ring with three hydroxyl groups at the 2, 4 and 6 positions, giving the molecule both weak acidic character and tautomeric versatility in solution. Typical industrial grades range from 98.0% to 99.5% purity, with the 99.0% specification representing a mid-to-high tier suitable for most commercial synthesis routes. The off-white colouration rather than pure white suggests trace organic impurities common in acid-precipitated batches, a standard observation that does not preclude use in regulated applications. Buyers should request a Certificate of Analysis with specific impurity profiling, as HPLC purity alone does not reveal residual solvent or heavy metal content.

Primary applications span pharmaceutical manufacturing of sedative-hypnotic and anticonvulsant barbiturates, research laboratory reagent use, and specialty chemical synthesis where the pyrimidine scaffold serves as a building block. Typical purchasers include generic API manufacturers, contract research organisations, and bulk chemical distributors serving European and North American formulators. Trade terms require direct confirmation with Hebei Hua-chem Group, as the listing presents no confirmed MOQ, packaging format, or preferred Incoterms; the supplier's location in Dongguang County, Hebei Province, places it within China's established northern chemical manufacturing belt with access to Tianjin Port for seafreight export.

Hebei Hua-chem Group operates from South Of Dongguang County, Dongguang 061600, Hebei Province, China, placing it in a region with concentrated chemical manufacturing infrastructure. The supplier profile carries a 'harbor' trust tier and 'imported' supplier tier classification, with both response rate and average response hours recorded at zero. These signals indicate limited active engagement data rather than verified trading history, a pattern common with marketplace-listed chemical traders rather than manufacturers with established export departments.

The listing provides no information on production capacity, R&D facilities, quality management certifications, or export experience. What the description does contain, a purity figure and melting point without supporting documentation references, suggests the supplier holds basic product knowledge but has not invested in detailed technical marketing. Buyers should treat Hebei Hua-chem Group as an unverified trading entity until direct due diligence confirms manufacturing capability or reliable sourcing relationships.
