  Provided is a matrix for MALDI mass spectrometry that has a high ability of ionizing low-molecular-weight compounds, and makes it possible to make measurement in a negative ion mode. The matrix is a matrix for mass spectrometry that contains one or more compounds selected from the group consisting of compounds each represented by the following general formula (I), (II) or (III), and their salts thereof. In the formulae (I), (II) and (III), X and Z are each C or N; R 1 and R 5 are each selected from the group consisting of H, an alkyl group, a (substituted) aryl group, a (substituted) arylalkyl group, and a (substituted) heteroaryl group; R 2 and R 6 are each selected from the group consisting of H, an alkyl group, an alkoxyl group, an amino group, a halogen atom, a nitro group, an allyl group, a (substituted) aryl group, and a (substituted) heteroaryl group; and R 7 and R 8 are each selected from the group consisting of H and an amino group provided that a case where R 1 =R 2 =H, and a case where R 7 =R 8 =an amino group are excluded.
