Stable label analogues of methotrexate (MTX) and 7-hydroxymethotrexate (7-OH-MTX) were required for use as internal standards for LC/MS quantitation. A minimum incorporation of stable isotopes to produce a mass increase of 3 in the non-glutamate derived portion of the molecule was necessary for adeq

Rate constants for the reactions of atomic oxygen ( 0 3 P ) with C&3F, C&IaCl,C@3Br, 1, l-CzHzFz, and I ,2-C&IzFz have been measured at 307' K using a discharge-flow system coupled to a mass spectrometer. The rate constants for these reactions are (in units of 1011cm3mole-1s-1)2.63 &0.38,5.22 =tO0.2
