Determination of Chemical Purity and Analysis of Menaquinone-7 (MK7)
Jedynak, Łukasz, et al. Journal of Pharmaceutical and Biomedical Analysis 135 (2017): 116-125.
The synthesis of menaquinone-7 (MK7) is a complex process that may produce many different MK7 isomers. The chromatographic behavior of these isomers is very similar, requiring the use of a chromatographic column with high selectivity for these similar compounds.
An HPLC method using a C30 reversed-phase analytical column with UV detection was developed to determine the chemical purity and analyze menaquinone-7 (MK7) in a single chromatographic run. This method allows for the separation and quantification of MK7 in the presence of its isomers.
Enantioselective Separation and Determination of Ibuprofen
Vashistha, Vinod Kumar, et al. Chirality 36.2 (2024): e23647.
Ibuprofen (IBP) is the 29th most prescribed drug in the United States in 2019 and is a widely used non-steroidal anti-inflammatory drug (NSAID) composed of two enantiomers, (R)-IBP and (S)-IBP, collectively referred to as (RS)-IBP. The enantioselective separation and determination of IBP enantiomers are crucial for pharmaceutical and clinical applications.
Chromatographic techniques used for the separation and determination of ibuprofen enantiomers include high-performance liquid chromatography (HPLC), gas chromatography (GC), liquid chromatography-tandem mass spectrometry (LC-MS/MS), and other techniques.
Analysis of Major Impurities in Ultra-Pure Bisphenol A
Krämer, Anke, Peter Bauer, and Felix H. Schacher. Journal of Chromatography A 1677 (2022): 463293.
Although the use of bisphenol A (BPA) and the production of polycarbonate (PC) through a condensation process are well-known, and the research on these processes has been ongoing for over 60 years, the understanding and quantification of side reactions during the polymerization process are still unresolved issues. Particularly, the purity of the raw material BPA greatly affects the properties of the resulting polymer.
A simple and reliable reversed-phase separation method has been developed for the separation of seven known bisphenol A (BPA) impurities, including 4-isopropenylphenol and its dimer isomers, o-, p-BPA, and triphenol. The method was validated using triple quadrupole mass spectrometry (qqqMS) and diode array detection (DAD).
