    en.wikipedia.org/wiki/4-Carboxybenzaldehyde

    4-Carboxybenzaldehyde (CBA) is an organic compound with the formula OCHC 6 H 4 CO 2 H. It consists of a benzene ring substituted with both an aldehyde and a carboxylic acid, with these functional groups on opposite corners of the ring. This compound is formed in 0.5% yield as a byproduct in the production terephthalic acid from p-xylene. Since ...

  6. 2-Carboxybenzaldehyde - Wikipedia

    en.wikipedia.org/wiki/2-Carboxybenzaldehyde

    2-Carboxybenzaldehyde is a chemical compound. It consists of a benzene ring, with an aldehyde and a carboxylic acid as substituents that are ortho to each other. The compound exhibits ring–chain tautomerism : the two substituents can react with each other to form 3-hydroxyphthalide, a cyclic lactol .

    Amygdalin 2 H 2 O HCN benzaldehyde 2 × glucose 2 × Benzaldehyde contributes to the scent of oyster mushrooms (Pleurotus ostreatus). Reactions Benzaldehyde is easily oxidized to benzoic acid in air at room temperature, causing a common impurity in laboratory samples. Since the boiling point of benzoic acid is much higher than that of benzaldehyde, it may be purified by distillation. Benzyl ...
