Product Description
Meglumine, also known as N-Methyl-D-glucamine or N-Methylglucamine, is an amino sugar derivative of sorbitol with the chemical formula C₇H₁₇NO₅ and CAS number 6284-40-8. Its molecular structure contains several hydroxyl groups and a secondary amino group, giving the compound a strongly hydrophilic character and acid–base functionality.
In pharmaceutical chemistry, Meglumine is used as a counterion, formulation excipient, and pH-adjusting component in selected applications. It can be combined with suitable acidic active ingredients to form meglumine salts, potentially changing properties such as aqueous solubility and formulation behavior. Its role in iodinated contrast-media salts is another established area of use.
Meglumine is generally supplied as a white to off-white crystalline powder or solid and is readily soluble in water. These characteristics make it relevant to aqueous formulation development, pharmaceutical ingredient processing, and chemical research. Actual performance depends on the compound being formulated, solution conditions, the selected grade, and the requirements of the final application.
For buyers evaluating Meglumine CAS 6284-40-8, the appropriate grade should be selected according to the intended use, assay requirements, impurity profile, and applicable quality standards.
