Product Overview
Sodium Formate, also known as sodium methanoate or formic acid sodium salt, is the sodium salt of formic acid. Its molecular formula is CHNaO2 (HCOONa), and its molecular weight is 68.007 g/mol. The CAS number is 141-53-7. It is generally supplied as a white crystalline powder or granular solid and is highly soluble in water.
Sodium Formate is an important industrial chemical used in a variety of manufacturing and processing applications. Its chemical characteristics make it useful in textile dyeing and printing, leather processing, oilfield operations, and other industrial formulations. It can also serve as a buffering component and as an intermediate in the production of formic acid. In selected industrial systems, it is used to support process stability and formulation performance.
The product is available in different grades and purity specifications depending on the intended application. Industrial-grade and laboratory-grade materials may differ in impurity limits, moisture content, and packaging requirements. Buyers should confirm the required purity, particle form, and technical specifications with the supplier before purchase
