L-Rhamnose monohydrate 98% Purity Natural Sugar Reference Standard CAS 6155-35-7 Research Grade Monosaccharide

• • • • • • Product Overview

            L-Rhamnose monohydrate is the hydrated crystalline form of the naturally occurring deoxy monosaccharide L-rhamnose (6-deoxy-L-mannose). The monohydrate form contains one molecule of water of crystallization per molecule of sugar, with the molecular formula C₆H₁₂O₅·H₂O and a molecular weight of 182.17 g/mol. It appears as white crystalline powder or needles with a characteristic sweet taste. This compound is widely used as a reference standard in carbohydrate analysis, as a precursor in glycoside synthesis, and as a component in various research applications involving bacterial fermentation and plant metabolism studies.

            Physical and Chemical Properties

            L-Rhamnose monohydrate is highly soluble in water and exhibits mutarotation in aqueous solution. It is stable under normal storage conditions and is commonly used as a more convenient form of L-rhamnose due to its crystalline stability and ease of handling.
