R 7 to R 10 may each represent H or C 1 -C 4 alkyl, R 1 (R 2 ), and R 3 (R 4 ) or R 1 (R 2 ) and R 5 (R 6 ) may jointly represent a carbocyclic ring system having 5-8 carbon atoms and m, n and p may be 0 or 1, are prepared by a variety of known methods...
This chapter discusses an optimized method to measure glycosylproteins: high performance liquid chromatography ( HPLC) assay of 5-hydroxymethyl-2-furfuraldehyde (5-HMF). The nonenzymatic glycosylation (NEG) is a well known post-translation modification of proteins that occurs by condensation of one ex...

The present invention to the development of a new spectrophotometric technique for predicting the dissolved 2-furfuraldehyde (2-FFA) in transformer oils. It is based on measurement of optical density of a colored complex formed by the addition of aniline and glacial acetic acid to service aged ...
The binding of aldehyde on free amino groups of protein takes place during the heating of 2-furfuraldehyde with casein. The reaction is of the 1st order, but becomes a 0 order reaction (with respect to amino groups) in the first reaction stage in case of sufficient excess of 2-fur...
The present invention relates to a method for preparing caprolactone, comprising converting 5-hydroxymethyl-2-furfuraldehyde by hydrogenation into at least one intermediate compound selected from the group of 2,5-tetrahydrofuran dimethanol, 1,6-hexanediol and 1,2,6-hexanetriol,and preparing caprolactone...
