Sodium chloride is a common inorganic salt used in laboratory research, industrial processes, and biological applications. Beyond the laboratory, it is consumed in large volumes for highway de-icing, water conditioning, food processing, textile dyeing, leather tanning and oil and gas exploration. It serves as a standard reagent for buffer preparation, cell culture, and analytical testing. Available in high purity, it has a CAS number of 7647-14-5, molecular formula NaCl, and molecular weight of 58.44 g/mol. Stored at ambient temperatures, it requires no special handling. Molekula supplies sodium chloride from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
