The deep eutectic mixtures (DESs), introduced as novel alternative to usual volatile organic solvents for organic
transformations has attracted a tremendous attention of the research community because of their low cost, negligible vapour
pressure, low toxicity, biodegradability, recyclability, insensitive towards moisture, and readily availability from bulk
renewable resources. Although, the low melting mixture of dimethyl urea (DMU)/L-(+)-tartaric acid (TA) is still infancy yet
much effective as it play double and triple roles such as solvent, catalyst and/or reagent in a same pot for many crucial
organic transformations. These unique properties of DMU/TA mixture prompted us to provide a quick overview of where
the field stands presently, and where it might be going in near future. To our best knowledge, no review dealing with the
applications of a low melting mixture of DMU/TA appeared in the literature except the one published in 2017 describing
only the chemistry of indole systems. Therefore, we intended to reveal the developments of this versatile low melting
mixture in the modern organic synthesis since its first report in 2011 by Köenig’s team to till date. Hopefully, the present
review article will be useful to the researcher working not only in the arena of synthetic organic chemistry but also to the
scientists working in other branches of science and technology.
