2448161-6	1988	Separation of G-CSF from GM-CSF was accomplished by the addition of trifluoroacetic acid to the mobile phase at the reverse-phase HPLC step.	Trifluoroacetic Acid	68-88	colony stimulating factor 2	Homo sapiens	25-31	
35523000-2	2022	The process involves a hitherto unknown 1,3-dipolar cycloaddition of nitronate to the aryne to give an unusual tricyclic nitroso acetal, in which the N-O bond of the isoxazoline ring is selectively cleaved upon the action of a base (CsF) or an acid (TFA).
