Products Description

What is 2-Butyl-1,2-benzisothiazolin-3-one CAS 4299-07-4 ?

2-Butyl-1,2-benzisothiazolin-3-one (CAS No. 4299-07-4), also known as 2-n-butyl-benzo[d]isothiazol-3-one and 2-butylbenzo[d]isothiazol-3(2H)-one, is a yellow transparent liquid with a slight odor. Its molecular formula is C₁₁H₁₃NOS, and its molecular weight is approximately 207.29 g/mol. This compound exhibits a boiling point of 170–175°C, density of 1.15–1.18 g/cm³ (or 1.165–1.175 g/mL at 25°C), pure compound pH of 2.5–3.5, and 5% aqueous solution pH of 7–9. It demonstrates extremely low solubility in water (≤1 mg/L at 20°C) while dissolving readily in organic solvents like benzene and toluene. With thermal stability exceeding 300°C and excellent UV resistance, it maintains effectiveness in high-temperature and outdoor environments.

Basic Info

Uses

As a broad-spectrum antimicrobial agent, 2-butyl-1,2-benzisothiazolin-3-one inhibits Gram-positive bacteria, Gram-negative bacteria, molds, yeasts, and algae with a minimum inhibitory concentration (MIC) of 2–125 ppm. Its primary uses include:

• Industrial sterilization: Preventing microbial contamination in metalworking fluids, coatings, adhesives, and inks.
• Polymer material protection: Providing microbial resistance to polyurethane (PU), polyvinyl chloride (PVC), silicone, polyethylene (PE), and polypropylene (PP) products such as shoe soles, artificial leather, automotive interiors, and building sealants.
• Agriculture and environmental protection: Serving as a mildew inhibitor for wood, paper, and other materials to reduce biological degradation.

Safety Information

• 2-Butyl-1,2-benzisothiazolin-3-one may be irritating to the respiratory system, skin and eyes.
• Avoid inhalation of dust and contact with skin and eyes.
• If symptoms of poisoning or accidents occur, seek medical attention immediately and provide relevant safety data to emergency personnel.
