The title compound (systematic name: 3-chloro-5-fluoro-2-hy-droxy-benzaldehyde), CHClFO, is a dihalogenated salicyl-aldehyde derivative that has been studied for its anti-bacterial characteristics. The salicyl-aldehyde engages in intra-molecular hydrogen bonding with an O-H⋯O distance of 2.6231 (19) Å while the mol-ecules pack together weak inter-molecular C-H⋯O, C-H⋯F and F⋯O inter-actions and offset face-to-face π-stacking.
标题化合物（系统名称：3-氯-5-氟-2-羟基苯甲醛），CHClFO，是一种二卤代水杨醛衍生物，已对其抗菌特性进行了研究。水杨醛通过O-H⋯O距离为2.6231 (19) Å的分子内氢键结合，而分子通过弱的分子间C-H⋯O、C-H⋯F和F⋯O相互作用以及面对面的错位π堆积聚集在一起。
