Bis(2,4,6-trihydroxyphenyl)methane, also known as pyrogallol or 1,3,5-trihydroxybenzene, is an organic compound with the chemical formula C6H6O3. It is a white crystalline solid that is soluble in water and has a characteristic sweet taste. bis(2,4,6-trihydroxyphenyl)methane is a trihydroxy derivative of benzene, meaning it has three hydroxyl groups (-OH) attached to the benzene ring. Pyrogallol is widely used in various applications, including as an antioxidant, a developer in photography, a reagent in chemical analysis, and a reducing agent in the synthesis of other organic compounds. It is also known for its ability to chelate metal ions, which makes it useful in the treatment of heavy metal poisoning. Due to its reactivity, pyrogallol can undergo a variety of chemical reactions, such as oxidation, condensation, and substitution, making it a versatile building block in organic chemistry.

5556-54-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5556-54-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,5,5 and 6 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 5556-54:
(6*5)+(5*5)+(4*5)+(3*6)+(2*5)+(1*4)=107
107 % 10 = 7
So 5556-54-7 is a valid CAS Registry Number.

Plasma-Polymerized Phlorotannins and Their Enhanced Biological Activities

Baek, Ki Ho,Jo, Cheorun,Kim, Hyun-Joo,Kim, Tae Hoon,Lee, Byong Won,Park, Sanghoo,Yong, Hae In

, p. 2357 - 2365 (2020)

Here, we investigated the effect of cold plasma (CP) on the biological activities of phloroglucinol. Phloroglucinol (7.92 and 15.84 mM in methanol) was treated with air dielectric barrier discharge plasma at 250 W. In vitro, 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical-scavenging activity and ferrous-reducing antioxidant power (FRAP) values of phloroglucinol increased in plasma treatment in a time-dependent manner. CP treatment of phloroglucinol decreased the lipid oxidation of oil emulsion during storage and increased the antimicrobial activity against Bacillus cereus, Escherichia coli O157:H7, and Staphylococcus aureus. Angiotensin-converting enzyme (ACE) inhibitory activity of phloroglucinol increased and total phenolic content decreased based on CP treatment. The CP-induced polymerization of phloroglocinol to phlorotannin derivatives was identified using high-performance liquid chromatography with UV detector and electrospray ionization/mass spectrometry (HPLC-UV-ESI/MS) method. Consequently, the polymer structure of phloroglucinol was found in the CP-treated phloroglucinol. In addition, CP enhances the biological activity of phloroglucinol and could be applied to bioactive materials in food and related industries.

Hydrogenation of substituted aromatic aldehydes: Nucleophilic trapping of the reaction intermediate, application to the efficient synthesis of methylene linked flavanol dimers

Boyer, Fran?ois-Didier,Ducrot, Paul-Henri

, p. 5177 - 5180 (2007/10/03)

The synthesis of dimeric flavanols is the consequence of the possible trapping of the reaction intermediates generated in the course of the reductive hydrogenation of substituted benzaldehydes. The scope of this reaction is investigated.
