2-Hydroxybenzoic acid (5.0 g, 0.04 mol) wasmixed without solvent with 2-phenoxyethanol (5.5 g, 0.04 mol) and refluxed for 4 hours. The reaction solution was left at room temperature for 24 hours under stirring. The raw product was collected as white powder in 60% yield. The crystal...
The crystal structure of the co-crystal: 2-hydroxybenzoic acid – N′-(butan-2-ylidene)pyridine-4-carbohydrazide, C10H13N3... C10H13N3O·C7H6O3, monoclinic, P21/n (no. 14), a = 7.4038(9) , b = 30.448(3) , c = 7.6744(8) , β = 112.013(3)°, V = 1603.9(3) 3, Z = ...
2COOH) > hydroxycinnamic acid (-CH = CHCOOH) > hydroxybenzoic acid (-COOH). Similarly, Natella et al. reported that hydroxycinnamic acid had stronger antioxidant activity than hydroxybenzoic acid when other substituents of benzene ring were the same...
(2 pyridyl)benzothiazole, H2odc = 4,4′-oxybisbenzoic acid, 1,4-H2ndc = naphthalene-1,4-dicarboxylic acid, Pta = terephthalic acid}, have been determined by single-crystal X-ray diffraction analysis, which shows that complexes 1–3 belong to monoclinic system with space group...

For the xylanase and cellulase treatments, total solubilized reducing sugars were measured using the 4-hydroxybenzoic acid hydrazide (PAHBAH) assay [62]. Briefly, 10 µL of the sample were mixed with 200 µL of the PAHBAH reagent, heated to 70°C for 30 min, and cooled to 4 °C, ...
Process for the selective preparation of a 2-hydroxybenzoic acid and a 4-hydroxybenzaldehyde and derivatives thereof The present invention concerns a process for the preparation of a 2-hydroxybenzoic acid and of a 4-hydroxybenzaldehyde and derivatives thereof from a mixture of two phenolic compounds, ...
2.1Dehydroprenyl-2-arylbenzofuran type MDAAs (Type A) Until now, 57 type A of MDAAs (1 − 57) have been discovered, which compose the biggest family in MDAAs. This type of MDAAs was found mostly in the plants ofMorus; its diene moiety was the dehydroprenyl group of 2-arylbenzo...
On the other hand, the 4-hydroxybenzoic acid derivative 4e (entry 5) was potent and had an IC50 of 1.72 mM, while its methylated analog 4d (entry 4) completely lost anti-invasive activity. This stressed the subtle bulkiness or polarity requirements at the 4-position of the phenyl ring. ...
