4-Methoxy-3-(trifluoromethyl)benzaldehyde is a fine chemical that can be used as a building block for pharmaceuticals and other organic compounds. It is also used in research for the synthesis of complex compounds. This chemical has been reported to be a useful intermediate or scaffold for organic syntheses. 4-Methoxy-3-(trifluoromethyl)benzaldehyde is soluble in water and ethanol, and insoluble in ether. It has a melting point of 140°C, boiling point of 249°C, density 1.096 g/cm³, and refractive index (20°C) 1.567.

4-Benzyloxy-2,6-dimethoxybenzaldehyde is a trypsin inhibitor. It has been shown to inhibit the activity of proteases, such as chymotrypsin and trypsin, by forming a covalent bond with the enzyme's active site serine residue. This inhibition blocks the cleavage of peptides at the carboxyl terminus. 4-Benzyloxy-2,6-dimethoxybenzaldehyde has been validated in different biological systems and has been used to study protein modifications and proteomics.

2-Chloro-7-methoxy-quinoline-3-carbaldehyde is a quinoline derivative that has been shown to have antiinflammatory activity in animal models of inflammatory diseases. 2CQA has been shown to bind to the CB2 receptor, which is one of the endocannabinoid receptors. The binding of 2CQA to the CB2 receptor can inhibit inflammation by inhibiting fatty acid production and reducing the production of proinflammatory cytokines that are responsible for inflammation. This drug also has potential as an analgesic agent in cancer pain management, as well as being useful in treating autoimmune diseases such as rheumatoid arthritis and pancreatitis. 2CQA is synthesized by reacting chloroacetyl chloride with 3-hydroxybenzoic acid (3HB). This reaction produces a carbonyl group at the position adjacent to the carbonyl group on the aromatic ring, which is then reduced with magnesium oxide.

3-Bromo-5-fluorobenzaldehyde is an intermediate in the synthesis of a variety of pharmaceuticals. It is used to manufacture drugs that have affinity for muscarinic receptors. In addition, 3-bromo-5-fluorobenzaldehyde can be used to synthesize drugs with affinity for nicotinic acetylcholine receptors, which are found in the autonomic nervous system. 3-Bromo-5-fluorobenzaldehyde is inexpensively made by chlorinating benzaldehyde and then reacting it with hydrogen fluoride. The synthesis has been optimized for high yield and purity by developing a method that produces impurities that are easily removed from the product. This process also provides an easy way to quantitatively measure drug substances and their binding affinities.

1,2-Dihydroacenaphthylene-5-carbaldehyde is a porphyrin that is water soluble and can be used to inhibit singlet oxygen. It has been shown to have an inhibitory concentration of 10 μM in cells. This compound has also been shown to have anticancer activity against breast cancer cells. The quantum yield of this compound is 0.02, which allows it to be used as a photosensitizer for photodynamic therapy (PDT). 1,2-Dihydroacenaphthylene-5-carbaldehyde has also been shown to kill cancer cells by inhibiting the production of reactive oxygen species (ROS) and DNA damage.
