3-Acetyl-4-hydroxy-6-methyl-2H-pyran-, 2-on, 25 g

3-Acetyl-4-hydroxy-6-methyl-2H-pyran-2-one is a pyranone derivative with CAS number 771-03-9 and empirical formula C₈H₈O₄. The compound has a molar mass of 168,15 g/mol and a flash point of 126,5 °C, supporting informed handling in synthetic and analytical workflows. It is offered by manufacturer Carl ROTH for laboratories that require a well-characterised oxygen-heterocycle building block. The structure is useful in route development, derivative preparation, and studies involving enolizable carbonyl systems or related natural-product-like scaffolds. Clear molar-mass and flash-point data assist with reaction design, solvent selection, and safety-conscious process planning. is practical for multi-step sequences, scale-up trials, and repeated experimental use in academic and industrial settings. Researchers working in fine chemicals, medicinal chemistry, or materials-oriented organic synthesis can integrate this pyran-2-one into programmes that demand consistent identity and documented physical properties.
