2,6-Dimethoxypyridine-3-carbaldehyde is a chemical that is used in the production of other chemicals. It is also used as an antifungal agent in vitro. 2,6-Dimethoxypyridine-3-carbaldehyde is activated by irradiation with ultraviolet light. The yield and reactivity are increased when it is used in the presence of catalysts such as thiosemicarbazide. Candida albicans and Aspergillus parasiticus can be inhibited by this compound at low concentrations. 2,6-Dimethoxypyridine-3-carbaldehyde has been shown to inhibit growth of Aspergillus on a petri dish, but not Candida albicans cells. This may be due to its inability to cross the cell membrane or because Candida albicans cells are able to synthesize their own pyridoxine (vitamin B6).

<p>3-Bromo-2-methylbenzofuran is a chiral compound that has been shown to stabilize the DNA of irradiated, homochiral DNA. It is also used as an intermediate in the synthesis of other compounds. 3-Bromo-2-methylbenzofuran has a high melting point, which makes it difficult to purify. The compound crystallizes unsymmetrically and fluoresces. It can undergo photochromism and isomerization under ultraviolet light. 3-Bromo-2-methylbenzofuran has a low solubility in water and can be toxic if inhaled or ingested. This compound exhibits fluorescence properties, which may be due to its ability to absorb light at wavelengths longer than 400 nm and emit light at wavelengths shorter than 400 nm.</p>

<p>5,8-dimethoxyquinoline is a nitrate that is used in the synthesis of heterocyclic compounds. It can be prepared by alkylation of 5,8-dimethoxybenzaldehyde with methyl iodide and sodium nitrite in the presence of ethanol or by the reaction of 2-nitropropane with benzaldehyde. The n-oxide of this compound has been shown to have activity against solid tumours and human lung carcinoma cell lines. 5,8-Dimethoxyquinoline reacts with dimethylhydrazone to form an unstable carbonyl intermediate which undergoes a 1,2-shift in nmr chemical shift.</p>
