Molisch's test is a sensitive chemical test, named after Austrian botanist Hans Molisch, for the presence of carbohydrates, based on the dehydration of the carbohydrate by sulfuric acid or hydrochloric acid to produce an aldehyde, which condenses with two molecules of a phenol (usually α-naphthol, though other phenols such as resorcinol and ...
12 Μαΐ 2024 · Molisch’s Test holds excellent significance in carbohydrate chemistry, particularly for detecting and identifying various sugars. The test can detect both simple and complex carbohydrates, making it a versatile tool for researchers in the field.
Molisch test provides a quick and reliable way to detect carbohydrates in a sample, signaled by the appearance of a purple ring during the reaction. Although the test confirms the presence of carbohydrates, further testing is needed to specify the type.
