4-Dialkylaminopyridines were soon found to have general applicability for catalysis of a wide variety of chemical reactions. 4-dimethylaminopyridine’s (DMAP) wide applicability has been frequently reviewed since the first review appeared in 1978.  The accelerating pace of reported applications for DMAP and the availability of DMAP in commercial quantities, at modest prices, have continued to stimulate great interest in its use as a catalyst in the fields of organic, polymer, analytical and biochemist

4-Dimethylaminopyridine Chemical Product Usage
1. A highly efficient catalyst for acylation reactions.
2. 4-Dimethylaminopyridine is a versatile hypernucleophilic acylation catalyst, it is used to improve the yield, reduce the reaction time, improving relaxation process conditions. Widely used in perfumes, dyes, pigments, pesticides, pharmaceuticals and polymer compounds and other fields. Also used as a catalyst for the synthesis of polyurethane, a curing agent and a blowing catalyst.
3. DMAP is a useful highly basic nucleophilic catalyst for a variety of reactions such as esterifications with anhydrides, the Baylis-Hillman reaction, hydrosilylations, tritylation, the Steglich rearrangement.
4. A highly fluorescent adenosine analogue, which in a dimethoxytrityl, phosphoramidite protected form, can be site-specifically inserted into oligonucleotides through a 3?5?phosphodiester linkage using an automated DNA synthesizer
