Poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) melt processed disks and solvent cast films were modified by graft co-polymerization with acrylic acid (AAc) in methanol solution at ambient temperature using gamma irradiation (dose rate of 4.5 kGy/h). To assess the presence of carboxylic acid groups

Pentafluorophenyl and phenyl silica stationary phases offer alternative selectivity compared to alkyl bonded C₁₈ and C₈ stationary phases, through other interactions such as π-π interactions, dipole-dipole and hydrogen bond interactions. Pentafluorophenyl and phenyl silica bonded stationary phases were efficiently prepared
Baseline separation of 15 taxanes including paclitaxel (Taxol) was achieved on pentafluorophenyl (PFP) HPLC columns. Methods using aqueous acetonitrile gradients on each of two commercial PFP columns were developed that are suitable for the determination of potency, content uniformity, and

An improved two-step synthetic route to functionalized cyclic carbonate monomers that features a novel cyclic carbonate intermediate with an active pentafluorophenyl ester group (MTC-OPhF(5)) has been developed. The versatile pentafluorophenyl ester intermediate can be synthesized on the gram to kilogram
