抗真菌和抗菌剂。 在一项研究中，2,3-二羟基苯甲醛被鉴定为靶向细胞壁的有效化学增敏剂。 此外，另一项研究证实了2,3-二羟基苯甲醛通过SOD2基因破坏了MAPK途径。 相同的研究还发现，当与其他抗真菌药（例如氟地西尼）一起使用时，它可以防止真菌突变体对氟地西尼产生耐受性。 还发现可用于合成Amberlite XAD树脂，该树脂可用于从土壤样品中预浓缩金属。 2,3-二羟基苯甲醛已被用于合成席夫碱的铜（II）配合物。它也被用于合成2-乙氧基-3-羟基-4-硝基苯甲酸 An antifungal and antimicrobial agent. In one study, 2,3-dihydroxybenzaldehyde was identified as a potent chemosensitizing agent that targets the cell wall. Furthermore, an additional study confirmed that 2,3-dihydroxybenzaldehyde disrupted the MAPK pathway via the SOD2 gene. The same study also found that when used with other antifungal agents such as fludioxonil, it prevented fungal mutants from developing tolerance to fludioxonil. Also found to be useful in synthesis of Amberlite XAD resins that can be used to preconcentrate metals from soil samples. 2,3-Dihydroxybenzaldehyde has been used to synthesize the copper(II) complex of Schiff base. It is also used to synthesize 2-ethoxy-3-hydroxy-4-nitrobenzoic acid
