Sodium Bromide Supplier — Industrial & Pharma Grade NaBr for Oilfield, Water Treatment & Pharmaceutical Applications

Sodium Bromide (NaBr, CAS 7647-15-6) is the most commercially significant inorganic bromide salt, widely used across oilfield drilling, water treatment, photographic processing, and pharmaceutical manufacturing as a versatile source of bromide ions. This white, crystalline, water-soluble compound is produced industrially through the direct reaction of bromine with sodium hydroxide or sodium carbonate, followed by crystallization and drying to achieve the desired purity grade. Sodium bromide’s primary industrial value lies in its ability to serve as a clear brine fluid in oil and gas completion and workover operations, where its high-density, corrosion-inhibiting, and solids-free characteristics make it superior to chloride-based brines in sensitive formations.

In water treatment, sodium bromide is used in conjunction with an oxidizer (typically hypochlorite) to generate hypobromous acid in situ — providing effective microbiological control in cooling towers, spa pools, and municipal water systems. The pharmaceutical industry utilizes sodium bromide as an intermediate in the synthesis of brominated organic compounds and historically as a sedative anticonvulsant. For procurement teams managing bromide supply for drilling operations, water treatment programs, or pharmaceutical synthesis, ensuring consistent purity, low moisture content, and reliable bulk logistics is critical to operational continuity. Davar ChemTech supplies sodium bromide in industrial, oilfield, and pharmaceutical grades with full analytical documentation.

Industrial Applications

In oilfield completion and workover operations, sodium bromide brines have become the clear brine fluid of choice for formations that are sensitive to solids invasion or chloride-induced corrosion. Unlike conventional drilling muds that contain suspended solids (barite, bentonite) capable of plugging formation pores and reducing permeability, sodium bromide brines are completely solids-free solutions that maintain formation integrity while providing hydrostatic pressure control. When blended with sodium chloride (NaCl) or calcium bromide (CaBr2), sodium bromide solutions can achieve densities ranging from 8.4 to 12.5 pounds per gallon (ppg), covering the vast majority of formation pressure gradients encountered in onshore and offshore wells across India’s sedimentary basins.

The oilfield-grade sodium bromide supplied by Davar ChemTech is specified with low chloride and iron content to minimize corrosion of downhole tubulars and surface equipment during extended exposure periods. In water treatment applications, the sodium bromide-hypochlorite system has proven particularly effective in cooling tower microbiological control programs. The mechanism involves in-situ generation of hypobromous acid (HOBr) through the reaction of sodium bromide with sodium hypochlorite (NaOCl) in aqueous solution. The resulting HOBr provides faster and more persistent microbial kill rates compared to hypochlorous acid alone, especially at alkaline pH values (pH 7.5–9.0) where cooling towers typically operate. This pH tolerance is a significant advantage, as it reduces the acid demand required to maintain effective chlorine-based disinfection, lowering both chemical consumption and corrosion risk.

Technical Specifications

Storage, Handling & Safety

Sodium bromide is generally classified as a low-to-moderate hazard chemical, but precautions are still necessary during handling. It is harmful if swallowed in significant quantities — ingestion of large doses can cause bromism, characterized by nausea, vomiting, ataxia, confusion, and in severe cases, neurological disturbances. Avoid inhalation of dust during bag opening and transfer operations by using local exhaust ventilation or wearing a dust mask. Wear chemical-resistant gloves, safety goggles, and protective clothing when handling sodium bromide powder or solutions.

Sodium bromide is hygroscopic and should be stored in tightly sealed containers in a cool, dry place to prevent moisture absorption and caking. In water treatment operations where sodium bromide is used with sodium hypochlorite, follow the oxidizer handling precautions for NaOCl and ensure proper ventilation of the dosing area. For oilfield brine mixing operations, wear appropriate PPE including chemical splash protection, as concentrated brine solutions can cause skin and eye irritation. Sodium bromide is not classified as a marine pollutant, but large releases into waterways should be avoided. Spills should be swept or vacuumed carefully to avoid dust generation, collected in sealed containers, and disposed of per local waste regulations.
