D(-)-Mannitol, min. 99 %, 250 mg, glass

D(−)-Mannitol is a monosaccharide polyol supplied at min. 99 % purity for biochemical and analytical laboratory use. It has the empirical formula C₆H₁₄O₆, a molar mass of 182,18 g/mol, CAS number 69-65-8, and EG nr. 200-711-8. This material is described as a standard for food regulatory methods and is packed as 250 mg in glass for precise small-scale weighing and reference preparation. Offered from manufacturer Carl ROTH, it suits carbohydrate chemistry, method calibration, comparative analytics, and research tasks that require a well-defined mannitol standard. The high minimum purity supports reproducible solution preparation and documentation in regulated or quality-controlled environments. Typical laboratory uses include preparation of reference solutions, chromatographic or spectroscopic checks, and biochemical experiments involving sugar alcohols. The compact 250 mg glass pack is practical when only limited amounts are needed per assay or validation run. Clear identity data—CAS number, empirical formula, and molar mass—help laboratories maintain accurate inventory records and method descriptions when D(−)-mannitol is specified as a standard or reagent in food-related and general analytical workflows.
