Product overview
What is 2,4-Dichloroaniline?
2,4-Dichloroaniline (2,4-DCA) is a dichlorinated aromatic amine — aniline with chlorines ortho and para to the amino group — used as an intermediate for agrochemicals, pharmaceuticals and azo colours. It supplies the 2,4-dichlorophenyl-amino fragment to actives such as the fungicide imibenconazole, and is reported as a raw material in routes to fluoroquinolone antibacterials.
With the formula C6H5Cl2N (CAS 554-00-7), 2,4-DCA is an off-white to beige crystalline solid melting at about 60 °C. It is produced mainly by hydrogenating 2,4-dichloronitrobenzene. It is one of six dichloroaniline isomers — the best-known sibling being 3,4-dichloroaniline, the herbicide aniline — and the dichloro analogue of Para Chloro Aniline.
Both chlorines survive downstream chemistry intact, so the isomer you buy is the isomer you get in the finished molecule — which is why producers specify 2,4-DCA closely by assay, by the 2,6-isomer and by monochloroanilines formed through over-reduction.
How it is made
1,3-Dichlorobenzene is nitrated to 2,4-dichloronitrobenzene, which is then hydrogenated over a catalyst chosen to limit dechlorination. The crude amine is distilled and flaked. Chlorination of acetanilide followed by hydrolysis is an alternative route.
What that means for your process
- Free amino group for acylation, diazotisation and condensation
- Both ring chlorines retained intact through downstream steps
- 2,6-Isomer and monochloroanilines controlled to grade, checked by GC
- Low moisture and colour for clean reactions and stable storage
Applications
What is 2,4-Dichloroaniline used for?
2,4-DCA is used as an intermediate in the synthesis of agrochemicals, pharmaceuticals, dyes and pigments. Its main applications, industry by industry, include:
Agrochemicals
Supplies the 2,4-dichlorophenyl group to selected fungicides and other crop-protection actives.
- Intermediate for the triazole fungicide imibenconazole
- Building block for herbicide and pesticide actives
Pharmaceuticals
A chlorinated aniline used in anti-infective and other API routes.
- Reported raw material for fluoroquinolone antibacterials such as ciprofloxacin
- Building block for API and custom synthesis
Dyes & analytical
Diazotised and coupled to give chlorinated azo colours.
- Diazo component for azo dyes and pigments
- Analytical reference standard for residue and water testing
Process route
How is 2,4-Dichloroaniline used downstream?
2,4-DCA enters a synthesis through its amino group — acylated, diazotised or condensed — while both ring chlorines ride through untouched into the finished active or colour.
2,4-Dichloroaniline
Charged as the dichlorinated amine. Assay and isomer content decide downstream purity.
C6H5Cl2NAcylation or diazotisation
The amine reacts with an acyl, thioacyl or nitrosating partner under controlled conditions.
Acyl / diazo partnerCoupling or ring build
The intermediate is coupled or elaborated into the heterocyclic or azo core.
2,4-Dichlorophenyl coreFinished product
Purified into the crop-protection active, API or colour, both chlorines intact.

Below is a detailed breakdown of where 2,4-DCA is used and the role it plays in each downstream product.
| Industry | Typical downstream products | Role of 2,4-DCA |
|---|---|---|
| Agrochemicals | Imibenconazole (triazole fungicide) | Aniline building block |

Safety
Is 2,4-Dichloroaniline hazardous?
Yes. 2,4-Dichloroaniline is toxic if swallowed, in contact with skin or if inhaled, causes serious eye damage, may cause an allergic skin reaction, may cause damage to organs through prolonged or repeated exposure and is very toxic to aquatic life with long-lasting effects. Like other chloroanilines it can cause methaemoglobinaemia. With correct PPE, ventilation and containment it is safely handled in industry.
2,4-DCA should be stored in sealed containers in a cool, dry, dark and well-ventilated place away from acids, acid chlorides, anhydrides and strong oxidisers. Keep it well below its melting point (about 60 °C) to prevent caking. Prevent release to drains and waterways. A full MSDS is supplied with every order.

- Keep containers sealed, cool, dry and out of direct light
- Store away from acids, acid chlorides, anhydrides and oxidisers
- Wash thoroughly after handling; no eating or drinking in work areas
- Never allow release to drains, soil or waterways

What is 2,4-Dichloroaniline used for?
2,4-DCA is used as an intermediate for agrochemicals such as the fungicide imibenconazole, in pharmaceutical routes including fluoroquinolone antibacterials, and as a diazo component for azo dyes and pigments. It is also used as an analytical reference standard.
What is the CAS number of 2,4-Dichloroaniline?
The CAS number is 554-00-7 and the molecular formula is C6H5Cl2N. It is also known as 2,4-DCA, 1-amino-2,4-dichlorobenzene or 2,4-dichlorobenzenamine.
How is 2,4-Dichloroaniline manufactured?
Mainly by catalytic hydrogenation of 2,4-dichloronitrobenzene, itself made by nitrating 1,3-dichlorobenzene. Chlorination of acetanilide followed by hydrolysis is an alternative route.
