white to almost white crystalline powder
Meglumine occurs as a white to slightly yellow-colored crystalline
powder; it is odorless or with a slight odor.
N-Methyl-D-glucamine is used in conjunction with iodinated organic compounds in contrast media viz. diatrizoate meglumine and iodipamide meglumine. It is useful in ion-exchange resins to chelate boron ions selectively. It is also used as an excipient in pharmaceuticals, in cosmetics and X-ray contrast media. It is also employed in the synthesis of surface active agents, pharmaceuticals and dyes.
excipient in cosmetics and X-ray contrast media
Meglumine is prepared by the imination of glucose and monomethylamine,
in an alcoholic solution, followed by catalytic
hydrogenation.
ChEBI: A hexosamine that is D-glucitol in which the hydroxy group at position 1 is substituted by the nitrogen of a methylamino group. A crystalline base, it is used in preparing salts of certain acids for use as diagnostic radiopaque media, whi
e its antimonate is used as an antiprotozoal in the treatment of leishmaniasis.
Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.
Meglumine is a glucose-derived secondary amine which is widely used as an excipient in pharmaceutical formulations.
Pharmaceutical Applications
Meglumine is an organic base used as a pH-adjusting agent and
solubilizing agent, primarily in the preparation of soluble salts of
iodinated organic acids used as X-ray contrast media.
Meglumine is widely used in parenteral pharmaceutical formulations
and is generally regarded as a nontoxic material at the levels
usually employed as an excipient.
LD50 (mouse, IP): 1.68 g/kg
Meglumine does not polymerize or dehydrate unless heated above
150°C for prolonged periods.
The bulk material should be stored in a well-closed container in a
cool, dry place. Meglumine should not be stored in aluminum
containers since it reacts to evolve hydrogen gas; it discolors if
stored in containers made from copper or copper alloys. Stainless
steel containers are recommended.
Crystallise N-methyl-D(-)-glucamine from MeOH. Its solubility in H2O is 10%. [Karrer & Herkenrath Helv Chim Acta 20 83 1957 also for other N-alkyl derivatives, Beilstein 4 IV 1914.]
Incompatible with aluminum, copper, mineral acids, and oxidizing
materials. Differential scanning calorimetry studies suggest meglumine
is incompatible with glipizide.
Included in the FDA Inactive Ingredients Database (injections; oral
tablets). Included in parenteral medicines licensed in the UK.
