Martius yellow is a compound with formula C₁₀H₆N₂O₅. It is a dye.

Martius yellow stains have been used to stain erythrocytes yellow, so they contrast well with red fibrin, in trichrome methods such as Lendrum's Picro Mallory and Slidder's Martius, Scarlet and Blue (MSB). It can be combined with other small molecular weight yellow dyes to increase stain intensity.

Synthesis: can be obtained by sulphonating in concentrated sulfuric acid (98%) and later nitration in nitric acid of p-naphtol, but never in a mix of both acids or direct nitration, or else the aromatic ring will break.
