What is Sodium selenite?

Sodium selenite 10102-18-8 is an inorganic compound with the chemical formula Na2SeO3. The salt is a colorless solid. The pentahydrate Na2SeO3 · 5H2O is the most common water-soluble selenium compound.

Synthesis

Sodium Selenite powder is usually prepared by the reaction of selenium dioxide with sodium hydroxide:

SeO2 + 2 NaOH → Na2SeO3 + H2O

After heating to 40°C, the hydrated compound is converted into anhydrous form.

Similar to sodium sulfite, Na2SeO3 has a pyramidal divalent anion SeO2−3. It can be oxidized to form sodium selenate, Na2SeO4.

Applications

• Like sodium selenate and zinc selenite, Selenite Sodium is primarily used in the production of colorless glass, where the pink tint produced by these selenite salts helps to neutralize the green color imparted by iron impurities.

• Because selenium is an essential element, sodium selenite is also used as a component in dietary supplements like multivitamin/mineral products, though supplements typically use L-selenomethionine or selenized yeast instead if only selenium is provided.

• The US FDA has approved selenium supplements for use in animal feed, with sodium selenite being the most common form used in pet food. According to one article, little was known about which selenium compounds were approved for use in animal feed when the decision was made in the 1970s to regulate their use, but only inorganic selenium salts (like sodium selenite and sodium selenate) could be used in animal feed where cost allowed when regulation was put into effect.

Safety

Selenium can be poisonous at high attention. For sodium selenite, the habitual poisonous cure in humans has been described as roughly2.4 to 3 milligrams of selenium per day. In 2000, the Institute of Medicine in the United States established a tolerable upper input position( UL) for selenium from all sources, including food, drinking water, and salutary supplements, at a attention of 400 micrograms per day. The European Food Safety Authority also reviewed the safety issue and set their UL for selenium at 300 micrograms per day.

It's important to note that exceeding these recommended situations of selenium input can lead to toxin symptoms, similar as gastrointestinal disturbances, hair loss, nail fineness, and neurological abnormalities. thus, it's pivotal to follow the recommended guidelines and consult with healthcare professionals for proper lozenge and supplementation.

Stability and storage

Selenite Sodium gmp is a fairly stable emulsion, but it can suffer corruption under specific conditions. Then are some explanations regarding the stability and storehouse conditions of sodium selenite

Stability Sodium selenite is fairly stable at room temperature, but it can degrade under high temperatures, direct sun, or sticky surroundings. It can reply with oxygen, acids, and other oxidizing agents, gradationally converting to selenate mariners.

Storage conditions: To ensure long-term storage and stability of sodium selenite, here are some recommended storage conditions:

• Temperature: Store at room temperature, avoiding high temperatures and freezing conditions.

• Light: Store in light-resistant containers, protecting it from direct sunlight.

• Humidity: Maintain a dry environment, avoiding moisture and high humidity.

• Packaging: Use well-sealed containers to prevent air, moisture, and other impurities from entering.

• Fire and explosion precautions: Since sodium selenite can react with other chemicals, it should be stored separately from flammable and explosive materials.
