Wego is a global supplier of Sodium Hypophosphite Monohydrate (SHP)

Wego Chemical Group is a leading global supplier and distributor of sodium salts such as Sodium Hypophosphite. The commonly used monohydrate can be found under CAS # 16721-80-5 and EINECS # 231-669-9. The anhydrous can be found as CAS # 7681-53-0, though the monohydrate is more commonly encountered and used. Sodium Hypophosphite has the molecluar formula NaPO2H2·H2O (or NaPO2H2 for the anhydrous). It is often referred to by its commonly used acronym, SHP,  and can also be referred to by its synonyms: Phosphinic Acid Sodium Salt and Sodium Phosphinate.

SHP appears as white crystals, and is an odorless substance. It is soluble in water, and very easily asborbs moisture from the air. This explains the relative prevalence of the monohydrate versus the anhydrous; the anhydrous often naturally hydrates using moisture in the air to form the monohydrate. Sodium Hypophosphite is the sodium salt of Hypophosphorous Acid; this material has large global commercial consumption, and is synthesized for industrial use by reacting Hypophosphorous Acid with a salt compound. Also of note, as of November 2001, SHP is classified as a List I chemical by the US DEA. 

Sodium Hypophosphite's primary use is in electroless nickel plating, which is an auto-catalytic process frequently utilized to coat high performance metals and plastics with nickel-phosphorus. SHP dehydrates nickel ions in an aqueous solution, reducing the substance to metallic nickel, thus coating these metals and plastics. This makes it particuarly helpful for coating irregular surfaces. Sodium Hypopohsphite is often used for this application in particular in aviation and in oil field. 

Other than coatings, usages of SHP include in the food and beverage industry as well as the animal food and feed industry—most notably as a food additive. Further uses of Sodium Hypophosphite include in agriculture, metal working, and water treatment, as well as in the production of construction materials, adhesives and sealants, pharmaceutical products, surfactants and emulsifiers, textile auxiliaries, plastics, resins and rubber, and flame retardants.

As a leading supplier and distributor, Wego provides efficient and reliable logistics management, handling, stocking, and delivery of chemical products like SHP, and can offer shipments in multiple packing sizes. Please contact Wego or request a quote or sample of Sodium Hypophosphite Monohydrate today.
