2-Butyl-1,2-benzisothiazole
Overview
2-Butyl-1,2-benzisothiazol-3(2H)-one (BBIT) is an organic compound primarily used as a biocide and preservative. It is highly effective against a wide range of microorganisms, including bacteria, fungi, and algae. Due to its stability and efficacy, BBIT is commonly incorporated into industrial products such as paints, coatings, and adhesives to prevent microbial degradation. BBIT is part of the isothiazolone family of biocides, known for their broad-spectrum antimicrobial properties. Its chemical structure allows it to remain active under various environmental conditions, making it a preferred choice for long-term preservation.
Physical and Chemical Properties
BBIT is a pale yellow to light brown liquid with a molecular weight of 207.29 g/mol. It is soluble in most organic solvents but has limited solubility in water. The compound has a density of approximately 1.1 g/cm³ and is stable under typical storage conditions. One of the key properties of BBIT is its broad-spectrum antimicrobial activity, which makes it effective in preventing spoilage and degradation in industrial applications. Its stability in various pH ranges and temperatures further enhances its utility as a preservative.
Main Applications
BBIT is widely used as a preservative in industrial and consumer products. In the paints and coatings industry, it prevents the growth of mold and bacteria, extending the shelf life of the products. It is also used in adhesives, sealants, and personal care items such as shampoos and lotions. Another significant application of BBIT is in water treatment systems, where it helps control microbial growth in cooling towers and other water-based systems. Its efficacy and stability make it a versatile biocide for various industrial processes.
Safety and Storage
BBIT should be handled with care to avoid health risks. Direct contact with skin or eyes can cause irritation, and inhalation of vapors should be avoided. Proper personal protective equipment (PPE), such as gloves and goggles, is recommended when handling this chemical. Storage conditions for BBIT include keeping it in a cool, dry, and well-ventilated area away from direct sunlight and heat sources. Containers should be tightly sealed to prevent contamination and evaporation. Compliance with local regulations for hazardous materials is essential for safe storage and disposal.
B2B Procurement Guide
When procuring BBIT, buyers should verify the CAS number (4299-07-4) and ensure the product meets purity specifications. It is advisable to source from reputable suppliers who comply with regional regulatory standards, such as REACH in Europe or EPA in the United States. Price ranges for BBIT typically vary between $50 and $100 per kilogram, depending on the quantity and supplier. Bulk purchases may offer cost savings, but buyers should also consider logistics and storage requirements. Technical support and documentation, such as safety data sheets (SDS), should be provided by the supplier.
