Product overview
What is 2,5-Dichloro Phenol?
2,5-Dichloro Phenol (2,5-DCP) is a chlorinated phenol used above all as the starting material for dicamba, one of the most widely used selective herbicides. The chlorine at position 5 leaves the position next to the hydroxyl free, which is what makes the carboxylation step to 3,6-dichlorosalicylic acid possible.
With the formula C6H4Cl2O (CAS 583-78-8), 2,5-DCP is a white to off-white crystalline solid that melts at about 58 °C and boils near 222 °C. It is only slightly soluble in water but dissolves readily in alcohols, ethers and aqueous caustic, where it forms the phenolate salt that the downstream chemistry actually uses.
Industrially it is obtained by the selective alkaline hydrolysis of 1,2,4-trichlorobenzene, which is why the two products are often bought together. Because the other dichlorophenol isomers give entirely different downstream products, buyers specify 2,5-DCP by isomer profile as closely as by assay.
How it is made
1,2,4-Trichlorobenzene is hydrolysed with aqueous caustic under pressure, which replaces one ring chlorine with a hydroxyl group and gives mainly the 2,5-isomer. The reaction mass is acidified to liberate the free phenol, then separated, distilled and flaked or packed molten to specification.
What that means for your process
- Low 2,4- and other dichlorophenol isomer content, checked by GC
- Low trichlorophenol and monochlorophenol carry-over
- Low moisture and controlled colour for clean carboxylation
- Flaked or molten form to suit your charging system
Applications
What is 2,5-Dichloro Phenol used for?
2,5-DCP is used almost entirely as a chemical intermediate. Its main applications, industry by industry, include:
Herbicides
The dominant outlet: carboxylation and methylation convert it into dicamba.
- Kolbe-Schmitt carboxylation to 3,6-dichlorosalicylic acid
- Methylation to dicamba (3,6-dichloro-2-methoxybenzoic acid)
- Dicamba salts and esters for formulation
Dyes & pigments
Chlorophenols are classic coupling and etherification substrates for colour chemistry.
- Chlorophenoxy ethers and esters
- Coupling components for azo colourants
- Intermediates for specialty pigments
Pharma & fine chemicals
A dichlorinated phenol handle for ether, ester and heterocycle synthesis.
- Aryl ether building blocks
- Chlorinated salicylic acid derivatives
- Custom chlorophenol derivatives
Process route
How is 2,5-DCP used to make dicamba?
The dominant route is Kolbe-Schmitt carboxylation. 2,5-Dichlorophenol is converted to its potassium phenolate, carboxylated with carbon dioxide under pressure to 3,6-dichlorosalicylic acid, and the phenolic hydroxyl is then methylated to give dicamba.

Charged and converted to the potassium phenolate. Assay and isomer profile decide downstream yield.

Safety
Is 2,5-Dichloro Phenol hazardous?
Yes. 2,5-DCP is harmful if swallowed, toxic in contact with skin, and causes severe skin burns and eye damage. It is also toxic to aquatic life with long-lasting effects. Like all chlorophenols it penetrates skin readily, so contact prevention matters more than any other single control.
2,5-DCP should be stored in sealed bags or drums in a cool, dry, ventilated place away from heat, strong bases, strong oxidisers and food materials, and handled with chemical-resistant gloves, goggles or a face shield, impervious protective clothing and dust or vapour respiratory protection. Molten product must be handled in closed, heated and properly vented systems. Prevent release to drains and waterways. A full MSDS is supplied with every order.

Safe-handling essentials
- Chemical-resistant gloves, goggles or face shield and impervious clothing
- Dust or vapour respirator; use local exhaust ventilation
- Avoid all skin contact — chlorophenols are absorbed through the skin
- Eyewash and safety shower within immediate reach of the charging point
- Handle molten material only in closed, heated, vented systems
- Keep bags and drums sealed, cool, dry and out of direct light
- Store away from strong bases, strong oxidisers and foodstuffs
- Never allow release to drains, soil or waterways
- Transport as UN 2020, class 6.1, packing group III

FAQ
Frequently asked questions
Common questions from buyers specifying 2,5-DCP for herbicide, dye and fine chemical production.
What is 2,5-Dichloro Phenol used for?
2,5-DCP is used mainly as the starting material for the herbicide dicamba, by way of carboxylation to 3,6-dichlorosalicylic acid and methylation. It is also used for chlorophenoxy ethers and esters in dye and pigment chemistry, and as a building block for pharmaceutical and fine chemical synthesis.
What is the CAS number of 2,5-DCP?
The CAS number is 583-78-8 and the molecular formula is C6H4Cl2O, with a molecular weight of 163.00 g/mol. Its EC number is 209-520-4 and the IUPAC name is 2,5-dichlorophenol.
How is 2,5-Dichloro Phenol made?
It is produced by the selective alkaline hydrolysis of 1,2,4-trichlorobenzene under pressure, which replaces one ring chlorine with a hydroxyl group. The reaction mass is then acidified to liberate the free phenol, which is separated, distilled and flaked or packed molten.
Is 2,5-Dichloro Phenol hazardous?
Yes. It is harmful if swallowed, toxic in contact with skin, causes severe skin burns and eye damage, and is toxic to aquatic life with long-lasting effects. Handle it with full PPE, ventilation and containment, and keep an eyewash and safety shower at the charging point; we supply a full MSDS with every order.
What is the difference between 2,5-DCP and 2,4-DCP?
Both are dichlorophenols with the same formula, but the chlorines sit differently. 2,4-Dichlorophenol is the intermediate for 2,4-D and related phenoxy herbicides, while 2,5-dichlorophenol leaves the position next to the hydroxyl open for carboxylation and is therefore the route to dicamba. They are not interchangeable, which is why the isomer content of each is controlled tightly.
How should 2,5-DCP be stored?
In sealed bags or drums in a cool, dry, well-ventilated store, away from heat, strong bases, strong oxidisers and foodstuffs, and out of direct light. Molten 2,5-DCP must be kept in closed, heated and properly vented systems.
Do you provide COA and MSDS for 2,5-DCP?
Yes, we provide a batch-specific COA and MSDS with every order, plus technical support on request.
Do you supply and export 2,5-Dichloro Phenol?
Yes, we supply 2,5-DCP across India and export internationally with complete dangerous-goods documentation, sourced from reliable manufacturers.
