Phosphorus Chemicals

OVERVIEW

Varsal’s Phosphorous chemical products are made at Varsal facilities or at Varsal approved partners.

We custom manufacture other phosphorous chemical upon request.  We also supply specially formulated electroless nickel plating chemicals. 

Sodium Hypophosphite, Monohydrate

  • Other names: sodium hypo
  • Appearance: White crystalline powder
  • Molecular weight: 105.99
  • CAS#: 10039-56-2

Used in electroless nickel plating applications, where a durable nickel-phosphorus film coats objects with irregular surfaces, such as in avionics, aviation and in oilfields.

Sodium hypo is also used in food additive applications as a stabilizer or emulsifier (e.g. cod-liver oil emulsions).

  • Electronics
  • Oil and gas
  • Industrial
  • Food

Varsal’s sodium hypo has extremely high purity with low residual impurities, leading to maximal yield and product quality for Varsal’s customers.

Hypophosphorus Acid (HPA)

  • Other names: Phosphinic Acid
  • Molecular weight: 66.00
  • Appearance: clear, colorless liquid
  • CAS#: 6303-21-5

HPA is a powerful reducing agent with a wide variety of uses in a variety of industries including:

Pharmaceutical: as a stimulant in API production

Industrial: as a wetting, dispersing, or emulsifying agent in electroplating, as a reducing agent, an antioxidant, as a decolorizing and color stabilization agent, as a neutralizing monobasic acid, and as a polymerization and polycondensation catalyst

Textiles: as a bleaching agent,  and used to produce hypophosphite salts used in wetting, dispersing, emulsifying and anti-static agents in synthetic fibers

  • Pharmaceutical
  • Electronics
  • Industrial
  • Textiles

Varsal’s HPA is produced from an ion-exchange process that treat negative ions like Chlorine and Sulfite, resulting in a high quality, high purity product with very low impurity content. We can control the impurities to customer-specified levels.

Phosphorus Pentoxide  (P2O5)

  • Other names: Phosphoric anhydride
  • Molecular weight: 141.94
  • Appearance: White powder
  • CAS#: 1314-56-3

Used as a strong drying dehydrating agent in various applications, including surfactants, extraction agents, glass, and organic synthesis routes in pharmaceuticals and pesticides.

  • Pharmaceutical
  • Agriculture
  • Industrial

Varsal’s P2O5 has extremely high purity with low residual impurities, leading to maximal yield and product quality for Varsal’s customers.

Nickel Hypophosphite, Hexahydrate

  • Other names:  I14-4713
  • Molecular weight: 296.67
  • Appearance: Light green crystalline powder
  • CAS#: 13477-97-9

Used as an intermediate.

  • Industrial

Varsal’s nickel hypophosphite is produced from a special process and has minimal impurities.

Tetrakis (Hydroxymethyl) Phosphonium Sulfate (THPS)

  • Other names:  NA
  • Molecular weight: 406.28
  • Appearance: clear, colorless liquid
  • CAS#: 55566-30-8

Used as a corrosion inhibitor and active ingredient for biocide formulations. THPS has low toxicity, is highly stable, easily dissolvable in water, and degrades quickly into a non-toxic substance.

  • Oil and gas
  • Water treatment
  • Paper and packaging

Varsal’s THPS is produced from a purified waste stream resulting in an economical, high quality product.

Tetrakis (Hydroxymethyl) Phosphonium Chloride (THPC)

  • Other names: NA
  • Molecular weight: 190.56
  • Appearance: Yellow liquid
  • CAS#: 124-64-1

Used as a precursor in the production of fire-retardant materials, and as a microbiocide and disinfectant in water systems and textiles.

  • Industrial
  • Water treatment
  • Textiles

Varsal’s THPC has extremely high purity with low residual impurities, leading to maximal yield and product quality for Varsal’s customers.
