The title compound, C16H20N2O2S2, crystallizes with two enantiomers (A and B) in the asymmetric unit. The most noticeable difference between these two molecules is the relative orientation of the benzothiazole rings, with S—C—C—S torsion angles

Low-methoxy ammonium pectinate (APC) and polygalacturonic acid (PG) could be transformed heterogeneously in a catalyst-free system very efficiently to the corresponding polysaccharide (PS) hydrazides. The hydrazide formation proceeds even at room tem

The ionic liquid 1-n-butyl-3-methylimidazolium chloride (BMIMCl) was found to be a non-aqueous solvent for the fast and efficient dissolution of polygalacturonic acid. Up to 5.3 wt% biopolymer could be dissolved by heating the mixture of biopolymer/B
