Application
1. Dibromoneopentyl glycol is a reactive flame retardant containing 60% aliphatic bromine, used primarily in unsaturated polyester resins for molded products and in rigid polyurethane foams .
2. DBNPG CAS 3296-90-0 offers high bromine content, excellent light stability, and good chemical resistance, making it increasingly used in CFC-free foam systems designed to meet stringent flame retardant standards .
3. Dibromoneopentyl glycol also serves as a starting material in pharmaceutical synthesis, such as in the three-step production of 1,1-cyclopropyldimethanol, a key intermediate for the asthma drug Montelukast .
Storage and Precautions
1. Store Dibromoneopentyl glycol in a tightly sealed container under inert gas in a cool, dry, well-ventilated area, protected from light and moisture as it is hygroscopic .
2. Keep DBNPG CAS 3296-90-0 away from strong oxidizing agents and incompatible materials, with recommended storage in a cool, dark place below 15°C .
3. Handle Dibromoneopentyl glycol using appropriate personal protective equipment including gloves, safety goggles, and protective clothing, washing thoroughly after handling .
Emergency response to leakage
1. Isolate the DBNPG CAS 3296-90-0 spill area, avoid dust generation, and wear full protective equipment including a suitable respirator when handling Dibromoneopentyl glycol .
2. Sweep up spilled Dibromoneopentyl glycol using non-sparking tools into sealed, labeled containers for disposal, and prevent entry into drains or waterways .
3. Personnel cleaning Dibromoneopentyl glycol spills must dispose of waste according to hazardous material regulations, noting that thermal decomposition releases toxic and irritant hydrogen bromide and bromine fumes .
Safety Information
1. Dibromoneopentyl glycol is classified with GHS signal word "Danger" and is harmful if swallowed (oral LD50 rat: 1,880-3,458 mg/kg), causes skin and serious eye irritation (H315, H319), and may cause respiratory irritation (H335) .
2. DBNPG CAS 3296-90-0 is suspected of causing cancer (H350, IARC Group 2B), genetic defects (H341, H340), and damaging fertility or the unborn child (H361, Category 2) .
3. Dibromoneopentyl glycol has a melting point of 109-111°C, is soluble in water (20-38 g/L at 25°C), decomposes at 235°C releasing toxic fumes, and is classified for transport with precautionary statements P201, P280, and P308+P313 .
