Product Overview
ChemSP supplies 4,5-Dichloro-N-octyl-3(2H)-isothiazolone to formulators, traders and research groups that need a documented, repeatable lot rather than an ad-hoc sample.
Its formula C11H17Cl2NOS corresponds to 11 carbon atoms, 17 hydrogen atoms, 2 chlorine atoms, 1 nitrogen atom, 1 oxygen atom and 1 sulfur atom; that fixed ratio is what makes lot-to-lot equivalence testable rather than a matter of judgement.
The molecular weight of 282.2 makes it a small molecule in the usual fine-chemical range, handled much like other solid or liquid intermediates of similar size.
Chemical Identity
| CAS Number | 64359-81-5 |
|---|---|
| Molecular Formula | C11H17Cl2NOS |
| Molecular Weight | 282.2 |
| LogP (calculated) | 4.9 |
| Melting Point | 40-46 °C |
| Catalog Category | Organic Chemicals |
Composition and Key Properties
Elementally the substance reads as a nitrogen- and oxygen-bearing framework (amide, amino acid or hydroxamate type), sulfur-containing functionality together with a halogenated framework.
The reported LogP of 4.9 is strongly oil-partitioning in character — relevant to extraction yields and to how much residue can be rinsed out of equipment.
Applications and Use Cases
4,5-Dichloro-N-octyl-3(2H)-isothiazolone (CAS 64359-81-5; formula C11H17Cl2NOS; 282.2 g/mol) is mainly applied in chemical synthesis, fine chemical manufacturing and related industrial processes.

- Coatings
- Fuels
- Metal working fluids (MUP only
- Resin emulsions
- Paints and various other specialty industrial products (as a preservative) and
- As a microbiocide in pulp/paper mills
These are uses on record, not a claim of suitability for any particular process. Whether the material fits a given application depends on the specification you set and on the regulations of the destination market.
Packaging and Handling
Supplied in standard export packaging appropriate to the physical form of the material. The exact pack size, inner liner and net weight are fixed on the order acknowledgement, since they depend on whether the lot ships as a solid, a paste or a liquid. Customers with drum, liner or pallet constraints should specify them when enquiring.
Quality and Documentation
Each shipment is accompanied by a certificate of analysis covering identity (IR or NMR as applicable), assay, and the parameters agreed in the specification. A safety data sheet in the current GHS format is issued with the first order and reissued whenever the classification changes.
Supply and Quotation
To quote accurately we need the quantity, the destination, and the specification you intend to work to. Enquiries sent with those three details usually come back priced within one business day.
Frequently Asked Questions
What is the CAS number of 4,5-Dichloro-N-octyl-3(2H)-isothiazolone?
The CAS registry number for 4,5-Dichloro-N-octyl-3(2H)-isothiazolone is 64359-81-5. Please quote it on any enquiry so that a quotation is matched to the correct grade.
Is 4,5-Dichloro-N-octyl-3(2H)-isothiazolone a stock item or made to order?
Availability moves with the production schedule, so it is confirmed at the time of enquiry. For repeat volumes a scheduled call-off arrangement is usually preferable to one-off orders.
Can you supply 4,5-Dichloro-N-octyl-3(2H)-isothiazolone with a specification we define?
Yes. The acceptance criteria can be adjusted within what the route allows — most often assay, moisture, heavy metals or particle size. Any change is written into the specification before the lot is released.

The table below is calculated from the molecular formula C11H17Cl2NOS. The values are theoretical and are intended as a reference for incoming inspection and for setting a purchase specification.
Contains the halogen Cl. Halogenated structures can release acidic vapour on heating or hydrolysis, so contact with bare metal surfaces should be controlled.
Contains nitrogen (1 atoms). Nitrogen-bearing structures are often amine-like: they can absorb carbon dioxide from air and develop odour if the packaging is not tight.
Contains sulfur. Sulfur-bearing materials may darken or develop odour under heat and should be kept away from oxidising agents.
At 282.22 g/mol the molar mass is in the small-molecule range, where volatility and dust generation are the practical handling concerns.
Identity and Registry Data
- CAS number
- 64359-81-5
Handling, Storage and Stability
Keep in corrosion-resistant, tightly closed containers. Halogenated material may release acidic vapour when heated or hydrolysed.
Store under ventilation with tightly closed packaging; amine-type nitrogen absorbs carbon dioxide from air and may develop odour.
Typical Specification Parameters
- Assay / content
- Loss on drying / moisture
- Appearance and odour
- Heavy metals (as Pb)
- Shelf life and packaging
These are the parameters normally reported on a certificate of analysis. Limits are lot-specific and follow the specification agreed between supplier and buyer; no numeric limits are stated or implied here.
