yellow crystalline powder | [Uses]
2,4-Dihydroxybenzophenone is an metabolite of Benzophenone (B204980), an compound used in the manufacturing of antihistamines, hypnotics and insecticides. | [Uses]
Ultraviolet light absorber, especially in paints and plastics. | [Description]
2,4-Dihydroxybenzophenone (DHP) is an organic compound derived from Garcinia xanthochymus, but there have been no reports on its biochemical functions and bioavailability. 2,4-dihydroxybenzophenone has been prepared by reacting resorcinol with benzoyl chloride or benzoic acid under anhydrous conditions in the presence of Friedel-Crafts catalysts such as AlCl3 or ZnCl2[1].
| [Definition]
ChEBI: 2,4-Dihydroxybenzophenone is a member of benzophenones. | [Preparation]
Obtained by condensation of benzanilide with resorcinol in the presence of zinc chloride and phosphorous oxychloride at 130–140° for 1 h (25%). | [Biological Activity]
2,4-Dihydroxybenzophenone has potential effects on the stimulation of osteoblast differentiation and mitigate PDS-induced osteoporosisthrough the activation of the β-catenin pathway. Moreover, 2,4-Dihydroxybenzophenone demonstrated a capacity to enhance the expression of crucial osteogenic markers, including RUNX2, OSX, and ALP[2].
| [Toxicology]
As a persistent and bioaccumulative compound, 2,4-Dihydroxybenzophenone (BP-1) exhibits estrogenic activity or anti-androgenic activity in vitro, which could pose potential risks to the ecological environment and human health. At present, there are a large amount of reports that concentrated on the biotoxicity of BP-1, mainly focusing on its endocrine disrupting effects and genetic toxicity. Endocrine-toxicological studies have shown that the toxicity of BP-1 is five times that of bisphenol A (BPA)[2].

Benzophenones (BPs), as UV filters, are widely utilized in personal care products such as sunscreen, body lotion and plastic products. 2,4-Dihydroxybenzophenone (BP-1) is a representative type of BP that has attracted wide attention owing to the high residues in the aquatic environment. According to previous studies, this compound can enter the aquatic environment through recreational water activities or incomplete removal in wastewater treatment plants (WWTPs). For example, BP-1 has been widely detected in seawater, groundwater, river water and WWTP effluents in Spain at concentrations ranging from 4.2 ng/L to 722.0 ng/L. More seriously, because of extensive human exposure through plastic products and sunscreen cosmetics, BP-1 has been detected in human urine, blood and milk[1]. |
