Product Overview

Dextrose Monohydrate AR (CAS No. 77938-63-7) is the crystalline monohydrate of D-glucose, an optically active reducing aldohexose containing one equivalent of water of crystallisation. In aqueous solution, glucose undergoes reversible anomeric interconversion and participates in characteristic carbohydrate reactions arising from its reducing functionality. Its ready solubility and importance as a metabolizable carbon source make it a widely used constituent of defined and complex microbiological media.

The AR grade, suitable for microbiology, is intended for analytical reagent preparation and microbiological procedures requiring controlled glucose quality. It serves as a fermentable carbohydrate and carbon source in culture media for bacteria, yeasts and other suitable microorganisms, supporting studies of microbial growth, carbohydrate utilisation and fermentation. It is also useful in preparing glucose-containing media for metabolic investigations and microbial biochemical tests, where glucose conversion may be evaluated through acid formation or other measurable metabolic products.
