Merck, W481911-1KG-K, meso-Erythritol

meso-Erythritol is a four-carbon polyol used in flavor-related research, sweetener formulation and analytical comparison of low-molecular-weight sugar alcohols. This food-grade material has a minimum assay of 99% and is supplied in a 1 kg package. Erythritol has a molecular weight of 122.12 g/mol and the molecular formula C4H10O4. Its small polyol structure, crystalline form and sweetness profile make it useful for assessing dissolution, crystallization and sensory-adjacent formulation variables in controlled research settings. In carbohydrate analysis, erythritol can be evaluated alongside other polyols such as xylitol and sorbitol, but their molar masses and chromatographic behavior differ. For comparison studies, prepare solutions on a mass or molar basis and keep temperature and water content consistent. The FG designation identifies the flavor/food-oriented grade; it does not replace the need to check batch documentation and intended-use regulatory requirements. The 1 kg unit supports repeated formulation trials and analytical sample preparation.
