Ortho-substituted building block
The OH group and the ortho chlorine give two handles for etherification, condensation and further substitution.
OCP
2-Chlorophenol (OCP) Supplier from China
2-Chlorophenol (ortho-chlorophenol, OCP) is a liquid intermediate for agrochemicals, pharmaceuticals and dyes, and a feed for further chlorinated and substituted phenols. SUNCHEM supplies OCP to synthesis users with a batch COA on every shipment.

Product overview & key benefits
2-Chlorophenol combines a phenolic OH group with a chlorine atom in the ortho position. Chemists use it to build ethers, esters and further chlorinated or substituted phenols that end up in herbicides, fungicides, pharmaceutical intermediates and dyes.
Chlorinating phenol gives a mixture of isomers, so the levels of 4-chlorophenol and dichlorophenols are usually what separates one OCP grade from another.
Handled as a liquid
OCP melts at about 9 °C, so it is pumped and metered as a liquid; drums may need gentle warming in cold weather.
Isomers on the COA
We quote against your limits for assay, 4-chlorophenol and dichlorophenols, with a batch COA for every lot.

Selection & comparison
Choosing the right OCP grade
| Your requirement | What usually works |
|---|---|
| Herbicide or fungicide synthesis | Specify assay and limits for 4-chlorophenol and dichlorophenols |
| Pharmaceutical intermediate | Ask for the TDS and a recent COA before sampling |
| Winter delivery to cold regions | Plan for drum warming; OCP solidifies at about 9 °C |
| Replacing an existing supplier | Send your current TDS or COA; we quote against the parameters you approve |
Packaging & storage
Packaging
Pack size and container type are confirmed with the quotation.
Storage
Store in closed containers in a cool, well-ventilated area away from oxidizers and bases. Strong odor; toxic by skin contact and ingestion — follow the SDS.
Transport
Regulated as toxic for transport (UN 2021, Class 6.1, PG III).
From first email to approved supply
Name the target molecule
Tell us what you make from OCP; the isomer limits that matter depend on your next step.
Compare the numbers that matter
Assay, 4-chlorophenol, 2,4- and 2,6-dichlorophenol, and water. Ask for them on the same COA template as your incoming inspection.
Plan handling and transport
OCP is toxic dangerous goods (UN 2021) and freezes near 9 °C. Agree container type and port early.
Trial, then lock the spec
Run a sample in your own process and keep the approved lot COA as the reference for contract limits.
