The original Molisch test relies on α-naphthol and concentrated sulfuric acid—chemicals now considered hazardous and outdated for many modern laboratories, especially educational ones. Modern "patches" have therefore focused on finding safer substitutes. For instance, has been proposed as a safer alternative to α-naphthol, potentially creating a thymol-based aldehyde-acid system. This and similar modifications aim to maintain the test's sensitivity while significantly reducing the safety risks associated with reagent storage and disposal. These safer alternatives are particularly important for adapting the test for use in school chemistry laboratories, where safety is paramount.

: Some non-carbohydrates, such as glycoproteins or certain organic acids (citric, lactic), can occasionally trigger a positive reaction.
