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]
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]
2,4-Dihydroxybenzaldehyde or β-resorcylaldehyde is a phenolic aldehyde, a chemical compound with the formula C 7 H 6 O 3. It is an isomer of protocatechuic aldehyde (3,4-dihydroxybenzaldehyde). References

The concentration in the blood peaked at 4 h reaching 6.5 ppm, this decreased to 2.6 ppm after 24 h. The elimination of half-life in blood was 22 h. Elimination took place for 90% through urine and 10% through faeces. After 72 hours 1.5% of the dose was still present in tissue. The highest concentration levels were present in liver, kidney and ...
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.
2,4-Dihydroxybenzoic acid (β-resorcylic acid) is a dihydroxybenzoic acid. As a resorcylic acid, it is one of the three isomeric crystalline acids that are both carboxyl derivatives of resorcinol and dihydroxy derivatives of benzoic acid. [4] Synthesis from resorcinol is via the Kolbe-Schmitt reaction. [5]
