New Chemical Entities

New Chemical Entities (NCEs) are molecules or ions produced by chemical synthesis.

Thanks to over 30 years’ experience in analytical sciences and all our laboratories (Bioanalysis (PK/TK/Immuno), Bioassays, Biochemistry, Chromatography, Elemental Impurities, Mass Spectrometry, Microbiology, Molecular Biology, Protein Characterisation) on one site, Quality Assistance holds a unique position on the market.

Quality Assistance provides you with the scientific support and all the analytical technologies needed to support your drug development process including NCE characterisation, development and validation of analytical methods, stability studies and batch testing.

Our capabilities in this area are summarized in the following table:
