87-56-9 Usage
Description
Mucochloric acid, also known as 2,5-dichloro-3,6-dihydroxy-p-benzoquinone, is an organic compound that serves as an intermediate product in the synthesis of the herbicide Burex. It exhibits strong oxidizing properties and has the potential to cause poisoning and skin damage upon exposure.
Uses
Used in Herbicide Production:
Mucochloric acid is used as an intermediate in the production of the herbicide Burex, which is effective in controlling the growth of unwanted plants and weeds in agricultural fields and other areas.
Used in Drinking Water Disinfection:
Mucochloric acid is also a chlorine disinfection byproduct found in drinking water. It possesses mutagenic activity, which can potentially cause harmful effects on human health. Therefore, it is essential to monitor and control the levels of mucochloric acid in drinking water to ensure its safety for consumption.
Safety Profile
Poison by ingestion.
Moderate skin and severe eye irritant.
Questionable carcinogen with experimental
tumorigenic data. Mutation data reported.
When heated to decomposition it emits
toxic fumes of Cl-.
Purification Methods
Crystallise the acid twice from water (charcoal). [Beilstein 3 IV 1720.]
Check Digit Verification of cas no
The CAS Registry Mumber 87-56-9 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 7 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 87-56:
(4*8)+(3*7)+(2*5)+(1*6)=69
69 % 10 = 9
So 87-56-9 is a valid CAS Registry Number.
InChI:InChI=1/C4H2Cl2O3/c5-2(1-7)3(6)4(8)9/h1H,(H,8,9)/p-1/b3-2+

The ozone-initiated oxidation of 1,2-dichlorobenzene catalysed by manganese supported on metal oxide (γ-Al2O3 and SiO2) at ambient temperature and pressure conditions is reported in this study. Wet impregnation method was used to synthesise various percentages of Mn loading on γ-Al2O3 and SiO2 supports. The catalysts were characterised by FT-IR, SEM, EDX, TEM, ICP-OES, BET and XRD techniques. All the reactions were conducted in an impinger glass reactor using 25 mL pure 1,2-dichlorobenzene and 0.25 g of the catalysts. The reaction products were characterised by GC–MS and FT-IR for quantitative and qualitative identification of the products. The 2.5, 5, 7.5 and 10 % of Mn impregnated on γ-Al2O3 and SiO2 were found to be more active than γ-Al2O3 and SiO2 supports. The 5 % Mn/SiO2 catalyst was found to be the most active catalyst in the ozonation reaction of 1,2-dichlorobenzene with a percentage conversion of 44 % and percentage selectivity of 88 % towards the main product mucochloric acid. Whereas, 5 % Mn/γ-Al2O3 catalyst resulted in the percentage conversion of 40 % and percentage selectivity of 86 % towards the main product mucochloric acid. The activity of the catalysts is attributed to manganese loaded on γ-Al2O3 and SiO2 supports.
