Carbonyl compounds are formed as reaction products.[2] Due to its higher stability, it has been proposed as an alternate solvent for methyl cellosolve for use in ninhydrin reaction.[3] Application Suitable for HPLC, spectrophotometry, environmental testing Other Notes Important notice - The article number 34869-4X2.5L will be discontinued.
