28520-00-5 Usage

General Description

2,4,5,6-tetrachlorobenzene-1,3-diol, also known as tetrachlorohydroquinone, is a chemical compound with the molecular formula C6H2Cl4O2. It is a chlorinated derivative of hydroquinone and is classified as a polyhalogenated aromatic compound. Tetrachlorohydroquinone is used in the production of dyes and pigments, as well as in chemical synthesis and as a laboratory reagent. It is considered to be toxic and poses health risks to humans and the environment. Exposure to this compound can cause skin and eye irritation, as well as respiratory and gastrointestinal issues. Furthermore, its persistence and bioaccumulation potential make it a concern for environmental contamination and potential harm to wildlife.

Check Digit Verification of cas no

The CAS Registry Mumber 28520-00-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,5,2 and 0 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 28520-00:
(7*2)+(6*8)+(5*5)+(4*2)+(3*0)+(2*0)+(1*0)=95
95 % 10 = 5
So 28520-00-5 is a valid CAS Registry Number.

Synthesis of Mn-doped TiO2 by novel route and photocatalytic mineralization/intermediate studies of organic pollutants

Umar, Khalid,Ibrahim, Mohamad Nasir Mohamad,Ahmad, Akil,Rafatullah, Mohd

, p. 2927 - 2945 (2019/02/19)

The doping of TiO2 particles with various manganese (Mn) concentrations (0.25–1.0%) were synthesized using simple sol–gel and modified sol–gel technique. The characteristics of synthesized particles were found employing standard analytical techniques such as X-ray diffraction, scanning electron microscopy and UV–Vis spectroscopy. The photocatalytic activity of the synthesized particles was compared by investigating the mineralization of two selected organic pollutants like ketoprofen and chlorothalonil. The photocatalysts which were produced by improved sol–gel technique show the lower value of band gap energy and small size crystallite and, hence, exhibit better photocatalytic activity. The outcomes also designate that the concentration of dopant Mn 0.75% indicated the highest photocatalytic activity than other concentrations of dopant in the mineralization of both the compounds. The mineralization kinetics of both compounds was studied under various situations like reaction pH and catalyst dosage. The mineralization rates were highly affected by all the above parameters. An effort has also been performed to highlight the intermediates produced during the photooxidation of both the compounds using the GC–MS analysis method. Both compounds show the production of several intermediates. A possible pathway for the production of different products has been suggested.
