28689-08-9 Usage
Description
1,5-Dichloro-2,3-dinitrobenzene is a highly toxic and potentially explosive chemical compound characterized by the presence of two chlorine atoms at the 1st and 5th positions and two nitro groups at the 2nd and 3rd positions on a benzene ring. It is known for its hazardous nature, requiring careful handling and disposal to prevent environmental contamination and harm to human health.
Uses
Used in Chemical Industry:
1,5-Dichloro-2,3-dinitrobenzene is used as an intermediate in the production of dyes, due to its ability to undergo various chemical reactions that facilitate the synthesis of a range of dye compounds.
Used in Agricultural Industry:
1,5-Dichloro-2,3-dinitrobenzene is used as a precursor in the manufacturing of fungicides and insecticides, where its toxic properties help control pests and diseases that affect crops.
However, due to its high toxicity and potential for explosion, the use of 1,5-dichloro-2,3-dinitrobenzene is strictly regulated, and alternative safer compounds are often preferred in these applications. It is crucial to handle this chemical with extreme care to minimize the risk of skin, eye, and respiratory irritation, as well as potential damage to the liver and kidneys.
Check Digit Verification of cas no
The CAS Registry Mumber 28689-08-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,6,8 and 9 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 28689-08:
(7*2)+(6*8)+(5*6)+(4*8)+(3*9)+(2*0)+(1*8)=159
159 % 10 = 9
So 28689-08-9 is a valid CAS Registry Number.

Process for the preparation of 4,6-diaminoresorcinol
-
, (2008/06/13)
4,6-diaminoresorcinol can be prepared in a plurality of steps in such a way that a) 1,3-dichlorobenzene is nitrated with a mixed acid of HNO3, H2 SO4 and SO3 at 0 to 40° C. in anhydrous H2 SO4, b) the resulting 1,3-dichloro-4,6/2,4-dinitrobenzene isomeric mixture is first reacted with benzyl alcohol in the presence of a strong base at -15° C. to +15° C. and then at 20° to 40° C. to give the dibenzyloxy compound and c) the 1,3-dibenzyloxy-4,6-dinitrobenzene isomer arising in pure form in b) is converted to the 4,6-diaminoresorcinol by catalytic hydrogenation.
