4,4′-Dihydroxybenzophenone is an organic compound with the formula (HOC 6 H 4) 2 CO. This off-white solid is a precursor to, or a degradation product of, diverse commercial materials. It is a potential endocrine disruptor. [1]
There are three structural isomers: 1,2-dihydroxybenzene (the ortho isomer) is commonly known as catechol, 1,3-dihydroxybenzene (the meta isomer) is commonly known as resorcinol, and 1,4-dihydroxybenzene (the para isomer) is commonly known as hydroquinone. [1]
The scientists analyzed blood, urine, feces, and tissue samples and found three metabolites: 2,4-dihydroxybenzophenone (DHB), 2,2-dihydroxy-4-methoxybenzophenone (DHMB) and 2,3,4-trihydroxybenzophenone (THB). [28] [29] To form DHB the methoxy functional group undergoes O-dealkylation; to form THB the same ring is hydroxylated. [27]
4-Hydroxyamphetamine; 4-Hydroxybenzaldehyde; 4-Hydroxybenzyl isothiocyanate; 4-Hydroxymandelic acid; 4'-Hydroxynorendoxifen; 4-Hydroxyphenylacetaldehyde; 4-Hydroxyphenylacetic acid; 4-Hydroxyphenylacetone; 4-Hydroxyphenylacetonitrile; Hyzetimibe
It is used as an intermediate in the synthesis of benzoyl chloride, benzotrifluoride and 2,4-dihydroxybenzophenone which in turn are also intermediates in other reactions: [2] C 6 H 5 CCl 3 + resorcinol → 2,4-dihydroxybenzophenone [3] [4] C 6 H 5 CCl 3 + H 2 O → C 6 H 5 C(O)Cl + 2 HCl [5] C 6 H 5 CCl 3 + 3 KF → C 6 H 5 CF 3 + 3 KCl [6]
4,4’-Difluorobenzophenone is an organic compound with the formula of (FC 6 H 4) 2 CO. This colorless solid is commonly used as a precursor to PEEK, or polyetherether ketone, a so-called high performance polymer. Because PEEK is resistant to attack, it is commonly used in carbon fiber coatings and cable insulation.
Sivifene (INN, USAN; developmental code name A-007) is a small-molecule antineoplastic agent and immunomodulator that was under development in the 2000s by Tigris Pharmaceuticals (now Kirax Corporation) as a topical treatment for cutaneous cancer metastases.
3,3’,4,4’-Benzophenone tetracarboxylic dianhydride (BTDA) is chemically, an aromatic organic acid dianhydride. It may be used to cure epoxy-based powder coatings. It has the CAS Registry Number of 2421-28-5 and a European Community number 219-348-1. It is REACH and TSCA registered. The formula is C 17 H 6 O 7 with a molecular weight of 322. ...
