Fungicide. Antimicrobial agent | [Definition]
ChEBI: A member of the class of 1,2-thiazole that is 1,2-thiazol-3-one substituted on the nitrogen (position 2) by an octyl group. A fungicide and antibacterial agent, it is used for treatment of canker and other fungal and bacterial diseases in fruit trees. It i
no longer approved for use within the European Union. | [Uses]
Fungicide. Biocide in cooling-tower water, paints, cutting oils, cosmetics and shampoo; for leather preservation. | [General Description]
Clear dark amber liquid. Used as a fungicide. | [Reactivity Profile]
2-OCTYL-3-ISOTHIAZOLONE(26530-20-1) reacts as an isothiocyanate. Isothiocyanates are incompatible with many classes of compounds, reacting exothermically to release toxic gases. Reactions with amines, aldehydes, alcohols, alkali metals, ketones, mercaptans, strong oxidizers, hydrides, phenols, and peroxides can cause vigorous releases of heat. | [Air & Water Reactions]
Insoluble in water. | [Potential Exposure]
Isothiazolone/isothiocyanate/heteroaramatic
fungicide and microbiocide used on textiles, in metalworking
fluids, and some water thinned paints. Its use as
a fungicide on cotton was canceled in the United States and
the tolerances were revoked in 1998. | [Fire Hazard]
This chemical is probably combustible. | [First aid]
Move victim to fresh air. Call 911 or emergency
medical service. Give artificial respiration if victim is not
breathing. Do not use mouth-to-mouth methods if victim
ingested or inhaled the substance; give artificial respiration
with the aid of a pocket mask equipped with a one-way
valve or other proper respiratory medical device?
Administer oxygen if breathing is difficult. Remove and
isolate contaminated clothing and shoes. In the case of contact
with substance, immediately flush skin or eyes with
running water for at least 20 minutes. For minor skin contact,
avoid spreading material on unaffected skin. Keep victim
warm and quiet. Effects of exposure (inhalation,
ingestion, or skin contact) to substance may be delayed.
Ensure that medical personnel are aware of the material(s)
involved and take precautions to protect themselves.
Medical observation is recommended for 2448 hours after
breathing overexposure, as pulmonary edema may be
delayed. As first aid for pulmonary edema, a doctor or
authorized paramedic may consider administering a drug or
other inhalation therapy. | [Shipping]
UN2922 Corrosive liquids, toxic, n.o.s., Hazard
class: 8; Labels: 8-Corrosive material, 6.1-Poisonous materials. | [Incompatibilities]
Oxidizers. Contact with hydrogen peroxide
may form explosive material. Isothiocyanates are
incompatible with many classes of compounds, reacting
exothermically to release toxic gases. Reactions with
amines, aldehydes, alcohols, alkali metals, ketones, mercaptans,
strong oxidizers, hydrides, phenols, and peroxides can
cause vigorous releases of heat. Ketones behave a weak
acid. Forms water soluble alkali metal salts. Ketones are
reactive with many acids and bases liberating heat and
flammable gases. The amount of heat may be sufficient to
start a fire in the unreacted portion of the ketone. Ketones
react with reducing agents such as hydrides, alkali metals,
and nitrides to produce flammable hydrogen gas and heat.
Ketones are incompatible with isocyanates, aldehydes, cyanides,
peroxides, and anhydrides. They react violently with
aldehydes, nitric acid, and perchloric acid. | [Description]
This isothiazolione, octylisothiazolinone, is contained
in relatively fewer products than other isothiazolinones. | [Waste Disposal]
Consult with environmental
regulatory agencies for guidance on acceptable disposal
practices. Generators of waste containing this contaminant
(≥100 kg/mo) must conform with EPA regulations governing
storage, transportation, treatment, and waste disposal.
Under 40 CFR 261.5 small quantity generators of this
waste may qualify for partial exclusion from hazardous
waste regulations. | [Production Methods]
Octhilinone is produced through a multi-step synthetic process that constructs the isothiazolinone ring and introduces the octyl side chain for antimicrobial activity. The synthesis typically begins with the reaction of octylamine and carbon disulfide, forming a dithiocarbamate intermediate. This is then cyclised with chlorinating agents such as chlorine gas or sulfuryl chloride, which help form the five-membered isothiazolinone ring by introducing the necessary sulphur and nitrogen linkages. | [Flammability and Explosibility]
Nonflammable | [Mechanism of action]
Inhibits fungal growth by inhibiting nucleic acid synthesis (DNA / RNA synthesis). | [Toxics Screening Level]
The initial threshold screening level (ITSL) for octylisothiazolone is 2 μg/m3 based on an annual averaging time. | [Pesticide Type]
