## Abstract The detection of waterβsoluble vitamins B~1~, B~2~, B~6~, B~12~ and C by matrixβassisted laser desorption/ionization (MALDI) timeβofβflight mass spectrometry (TOFMS) was attempted by studying 17 porphyrin matrices. Comparative studies of porphyrin matrices, useful mass spectral window,
nic acid (11), a-cyano-4-hydroxycinnamic acid (12), 2-Fifteen sugar osazones were synthesized and evaluaminobenzoic acid (13), 3-hydroxypicolinic acid ( ), 3ated for their use as matrix-assisted laser desorption/ aminoquinoline (3-AQ) (15), 2,5-dihydroxybenzoic acid ionization matrices. Various carb
