4 dimethylaminopyridine
1. Description
4-Dialkylaminopyridines were soon found to have general applicability for catalysis of a wide
variety of reactions. 4-dimethylaminopyridine’s (DMAP) wide applicability has been frequently
reviewed since the first review appeared in 1978. [3] 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

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
