Fehling’s Reagent A Solution AR 500ml

SKU : L-1238.0500
CAS : 7758-98-7
Formula : CuSO4
Grade : AR

In organic chemistry, Fehling’s solution is a chemical reagent used to differentiate between water-soluble carbohydrate and ketone (>C=O) functional groups, and as a test for reducing sugars and non-reducing sugars, supplementary to the Tollens’ reagent test. The test was developed by German chemist Hermann von Fehling in 1849.

Fehling’s solution can be used to distinguish aldehyde vs ketone functional groups. The compound to be tested is added to the Fehling’s solution and the mixture is heated. Aldehydes are oxidized, giving a positive result, but ketones do not react, unless they are α-hydroxy ketones

Fehling’s reagent is a chemical solution used to test for the presence of reducing sugars and other compounds with aldehyde functional groups. It is a mild oxidizing agent prepared by mixing two separate solutions: Fehling’s A (a solution of copper (II) sulfate) and Fehling’s B (a solution of potassium sodium tartrate and sodium hydroxide). When heated with a sample containing reducing sugars, it forms a red precipitate of copper(I) oxide, indicating a positive result.Principle: The copper(II) ions in the reagent are reduced to copper(I) ions by the reducing sugar. This reaction forms a brick-red precipitate of copper(I) oxide (𝐶𝑢2𝑂).Uses: It is used to test for the presence of reducing sugars, like glucose, and to differentiate between aldehydes and ketones.Result: A positive test is indicated by the formation of a red precipitate.

Hello
Can we help you?
Labotiq focuses on a practical and precise field: laboratory supplies, chemical reagents, equipment, and plastic labware. This kind of work is all about accuracy, safety, and trust, because even small details can affect the final result. The same idea is becoming more relevant in digital entertainment, where choosing a platform also means paying attention to reliability, transparency, and user protection.Online entertainment has turned into an everyday habit, from streaming and mobile games to casino-style platforms and interactive services. Still, a good digital experience starts with clear rules, secure payments, licensed operators, and easy-to-understand information. Anyone interested in safe online leisure and the Spanish gambling market can find a useful reference in mejores casinos en España. The topic is not only about fun, but also about choosing platforms carefully, understanding how regulation works, and avoiding random decisions when money and personal data are involved.That creates a simple connection between the two areas. Labotiq supports laboratories with dependable products for controlled work, while trusted information about digital entertainment helps users feel more confident online. When reliability comes first, both laboratory processes and online services become easier to understand, safer to use, and more valuable in everyday life.
