A generic approach for the determination of residues of alkylating agents in active pharmaceutical ingredients by in situ derivatization-headspace-gas chromatography-mass spectrometry.

Roberto Alzaga et al.

Journal of pharmaceutical and biomedical analysis, 45(3), 472-479 (2007-08-28)

A simple, reliable and fast procedure for the simultaneous determination of residues of some common alkylating agents (AAs), such as mesylates, besylates, tosylates and sulfates, employed in drug synthesis, has been developed by in situ derivatization-headspace-gas chromatography-mass spectrometry. Pentafluorothiophenol is

Determination of methyl and ethyl esters of methanesulfonic, benzenesulfonic and p-toluenesulfonic acids in active pharmaceutical ingredients by solid-phase microextraction (SPME) coupled to GC/SIM-MS.

Ivelisse Colón et al.

Journal of pharmaceutical and biomedical analysis, 39(3-4), 477-485 (2005-06-14)

The development, optimization and validation of an extraction method for methyl and ethyl esters of various sulfonic acids is presented. The extraction and determination of these esters in active pharmaceutical ingredients (APIs) was accomplished using solid-phase microextraction coupled to GC/MS

Characterization in humans of 18F-MNI-444, a PET radiotracer for brain adenosine 2A receptors.

Olivier Barret et al.

Journal of nuclear medicine : official publication, Society of Nuclear Medicine, 56(4), 586-591 (2015-02-24)

PET with selective adenosine 2A receptor (A2A) radiotracers can be used to study a variety of neurodegenerative and neuropsychiatric disorders in vivo and to support drug-discovery studies targeting A2A. The aim of this study was to describe the first in
