Mebicar (Tetramethylglycoluril) — Laboratory Reagent CAS 10095-06-4
WARNING: Chemical reagent intended solely for laboratory, research and analytical purposes. NOT FOR HUMAN OR ANIMAL CONSUMPTION. It is not a medicinal product, dietary supplement or food.
Mebicar (also known as Mebikar) is a bicyclic urea-derived compound belonging to the glycoluril class, formally designated 2,4,6,8-tetramethyl-2,4,6,8-tetraazabicyclo[3.3.0]octane-3,7-dione. The molecule consists of two fused imidazolidinone rings linked by a bridging bond, with all four nitrogen atoms bearing methyl substituents. This symmetrical, rigid framework makes the compound chemically stable and well defined crystallographically, which renders it a convenient standard in analytical and preparative work.
The supplied material is a uniform, white crystalline powder of high declared purity. As a glycoluril derivative, Mebicar is a representative example of bicyclic urea systems, which in organic chemistry provide an interesting scaffold for studies of molecular recognition and supramolecular chemistry.

Research applications
In the laboratory, Mebicar is used as a reference material and as a subject of structural studies on glycoluril chemistry. Owing to its well-defined, symmetrical structure it serves as a convenient standard in NMR and IR spectroscopy, allowing characteristic signals of the N-methyl groups and the carbonyls of the bicyclic system to be tracked. Compounds of the glycoluril family are the focus of work in supramolecular chemistry and the synthesis of molecular scaffolds, so pure Mebicar can act as a model substrate in N-substitution reactions and studies of complex formation.
The material finds use in analytical methodology as a standard for the calibration and validation of chromatographic methods (HPLC, GC) and in the development of purity assay procedures. It is also employed in educational work illustrating the structure and reactivity of bicyclic urea derivatives. All applications are strictly research and analytical in nature; the product is not intended for any use on living organisms. Store in a dry, cool place, in a tightly closed container, away from moisture and heat sources.
