The title compound, dimethyl 2,2'-(oxalyldiimino)diethanoate, C(8)H(12)N(2)O(6), exhibits a network of hydrogen bonds between amide and ester groups. Molecules lie on inversion centres and show a planar conformation for both the oxalamide and ester groups. The glycine residues adopt a conformation close to the polyglycine II structure.

Chitosan and its derivatives have attracted great attention due to their properties beneficial for application to wound healing. The main focus of the present review is to summarize studies involving chitosan and its derivatives, especially N,N,N-trimethyl-chitosan (TMC), N,O-carboxymethyl-chitosan (CMC) and O-carboxymethyl-N,N,N-trimethyl-chitosan (CMTMC), used to accelerate wound healing. Mor...

Pure organic substances are the first and key link in chain of metrological traceability analysis. In most cases, purity determination substance is a non-trivial task, solution which requires preliminary theoretical study understanding capabilities instrumental methods for developing pertinent analytical procedure. Within study, an algorithm determining separate group compounds – ortho-phthalic...
