Description
Copper naphthenate is a copper carboxylate made with naphthenic acid, which is a by-product of petroleum. It is a blueish-green solid that exhibits a wide range of efficacy against decay fungi, termites, and various wood-destroying insects, making it a general-use wood preservative. Additionally, it is used as a textile preservative and has been safely utilized in greenhouse applications.
Uses
Used in Wood Preservation Industry:
Copper naphthenate is used as a wood preservative for its wide-ranging efficacy against decay fungi, termites, and wood-destroying insects. It helps protect wood from damage and extends its lifespan.
Used in Textile Industry:
Copper naphthenate is used as a textile preservative, providing protection against fungal and insect damage, thus enhancing the durability and longevity of textile products.
Used in Greenhouse Applications:
Copper naphthenate has been used safely in greenhouse applications, where it helps protect plants from fungal and insect threats, promoting healthier growth and higher crop yields.
Used in Beekeeping:
Copper naphthenate is recommended for the treatment of beehives, as it has not been found to harm bees or significantly affect the quality of honey produced.
Used in Livestock Industry:
Livestock exposed to copper naphthenate-treated shelters and water troughs have shown no adverse health effects, making it a safe option for use in animal husbandry.
Used in Veterinary Medicine:
Copper naphthenate is approved as an over-the-counter topical treatment for treating horses and ponies for thrush at concentrations of 37.5%.
Used in Agricultural Industry:
Copper naphthenate serves as a fungicide and insecticide, acting as a mercaptan scavenger in technical pesticide formulations. It is registered for use in the U.S. but not listed for use in EU countries.

Preparation
Copper(II) naphthenate is prepared by the reaction of copper(II) hydroxide or basic copper(II) carbonate with naphthenic acid in a hydrocarbon solvent or by the reaction of copper(II) sulfate with sodium naphthenate. It is insoluble in water. It is used to control fungi and mildew in textiles, woods, and in antifouling pigments. Copper(II) naphthenate is usually marketed as a solution containing 8% copper.
Hazard
Flammable, moderate fire risk (solution).
Toxic by ingestion and inhalation.
Health Hazard
Recommended Personal Protective Equipment: Goggles or face shield; plastic gloves (as for gasoline); Symptoms Following Exposure: Vapor causes mild irritation of eyes and mild irritation of respiratory tract if inhaled. Ingestion causes irritation to stomach. Aspiration causes severe lung irritation and rapidly developing pulmonary edema; central nervous system excitement followed by depression; General Treatment for Exposure: INHALATION: remove victim to fresh air. EYES: wash with copious amounts of water for at least 15 min. SKIN: wipe off and wash with soap and water. INGESTION: do NOT induce vomiting; guard against aspiration to lungs. ASPIRATION: enforce bed rest; give oxygen: call a doctor; Toxicity by Inhalation (Threshold Limit Value): 500 ppm; Short-Term Exposure Limits: Data not available; Toxicity by Ingestion: Grade 1; oral rat LD50= 4-6 g/kg; Late Toxicity: Data not available; Vapor (Gas) Irritant Characteristics: Vapors are non-irritating to the eyes and throat; Liquid or Solid Irritant Characteristics: Minimum hazard. If spilled on clothing and allowed to remain, may cause smarting and reddening of skin; Odor Threshold: Data not available.

Check Digit Verification of cas no
The CAS Registry Mumber 1338-02-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,3 and 8 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1338-02:
(6*1)+(5*3)+(4*3)+(3*8)+(2*0)+(1*2)=59
59 % 10 = 9
So 1338-02-9 is a valid CAS Registry Number.
