The Schiff bases of chitosan were synthesized by the reaction of chitosan with 3-(4-
substituted-phenyl)-1-phenyl-1H-pyrazole-4-carbaldehyde. The structure of the prepared …

Three heteroaryl pyrazole derivatives; namely 1-phenyl-3-(thiophene-2-yl)-1H-pyrazole-4-
carbaldehyde, 1-phenyl-3-(furan-2-yl)-1H-pyrazole-4-carbaldehyde and 1-phenyl-3 …

In this work, a novel series of Schiff base has been reported by the reaction of Chitosan with
different substituted pyrazole-4-carbaldehydes in acidic media. The synthesized compounds …

Recently, there have been significant scientific interests to scientists for the chemical
modifications of chitosan to increase its applications. The main objective of this study was to …

Schiff's base of chitosan (BCTS) was obtained by the reaction of chitosan (CTS) and
benzaldehyde. Then BCTS reacted with acyl chloride which was synthesized by p …

In the present study, Chitosan Schiff Bases (CSBs) were synthesized via condensation
reaction of Low Molecular Weight Chitosan (LMWC) with aromatic aldehydes including …

C 6-Schiff bases derivatives of chitosan were synthesized for the first time. C 2-amino groups
and C 3-hydroxy groups were firstly protected by CuSO 4· 5H 2 O, and the C 6-hydroxy was …

Chitosan, a biocompatible, biodegradable, nontoxic polymer, is prepared from chitin, which
is the second most naturally occurring biopolymer after cellulose. Schiff base of chitosan …
