Biuret (CAS 108-19-0) is an organic compound primarily used as a non-protein nitrogen source in ruminant feed. It is also used in the manufacture of urea fertilizers and as a reagent in analytical chemistry. It also serves as a precursor in the synthesis of pharmaceuticals, agrochemicals, and specialty polymers. This white crystalline solid has the molecular formula C2H5N3O2 and a molecular weight of 103.08 g/mol. It is stable under ambient storage conditions but requires careful handling, as it carries a warning signal word for potential skin and eye irritation. Molekula supplies Biuret from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
