Highly chemo- and regioselective acylation of 2-aminopentane-1,5-diol derivatives has been achieved by organocatalysis. An acyl group can be chemoselectively introduced onto the sterically hindered secondary hydroxy group in the presence of the primary one by virtue of the molecular recognition

Calcium alginate microspheres were prepared by an emulsification method and cross-linked with various aldehydes using different methods. Methanal and pentanedial produced low aggregation of microspheres while octanal and octadecanal produced the opposite effect. The latter two aldehydes displaced very little

The use of pentane-1,5-diol in topical pharmaceutical products is relatively new compared with, e.g., propane-1,2-diol (propylene glycol), also an aliphatic diol, which has been used for many years. Yet, what are the differences between diols in clinical efficacy, safety and

The size of silver nanocrystals in polyol synthesis can be simply controlled by tuning the viscosity of the reaction medium such as ethylene glycol, 1,2-propanediol, 1,4-butanediol and 1,5-pentanediol. We found that a higher viscose medium (1,5-pentanediol) led to monodispersed smaller
