Sodium Selenate TCI O0698

TCI O0698 Sodium Selenate is an inorganic salt in which selenium sits at its highest oxidation state, +6. In selenium chemistry it is the natural counterpart to sodium selenite, and the two compounds are often studied side by side. Laboratories use sodium selenate as a water-soluble source of selenium for research in plant and animal nutrition, cell biology, toxicology, and selenium speciation analysis. Like other soluble selenium compounds, it is highly toxic and must be handled under strict safety discipline.

Selenate and selenite have different oxidation states, and this changes how they behave chemically and biologically. Selenate tends to resist reduction better than selenite and moves more easily through soil. Because its structure resembles the sulfate ion, many plants take selenate up through sulfate transporter pathways. This is why sodium selenate is widely used in biofortification research and in studies of how plants absorb selenium. For analysts, it is an important selenium(VI) reference compound when developing methods to separate selenium species.

In Indonesia, sodium selenate is relevant to agronomy and soil science laboratories that study micronutrient fertilisation and biofortification of food crops. University research groups in plant physiology, animal nutrition, and environmental science can use it as a defined selenium(VI) source in controlled experiments. Analytical laboratories working on selenium speciation can also use it as a reference material for method development. In every case, Indonesian laboratories should follow strict protocols for handling highly toxic selenium compounds.

• Plant nutrition and biofortification research: selenate is taken up through sulfate transporter pathways, which makes it a suitable selenium source for studying how crops absorb and accumulate selenium.
• Selenium speciation analysis: as a selenium(VI) reference compound, it helps analysts develop and validate methods that separate selenate from selenite and other selenium species.
• Soil science studies: selenate is relatively stable against reduction and moves easily in soil, so it is useful for experiments on selenium mobility and availability in different soil systems.
• Animal nutrition and cell biology research: it dissolves in water, giving researchers a convenient way to supply selenium to experimental diets, culture systems, or biological assays.
• Toxicology studies: as a highly toxic soluble selenium compound, it is used in controlled research to examine how selenium(VI) affects living systems differently from selenium(IV).

• Product code: O0698

Store sodium selenate in its original, tightly sealed container in a cool, dry, well-ventilated place, away from incompatible materials and reducing agents. Keep it in a locked or restricted cabinet for highly toxic chemicals, and label it clearly. Handle it only in a fume hood or another well-ventilated area, and wear chemical-resistant gloves, safety goggles, and a laboratory coat. Do not inhale the dust, and avoid any contact with skin or eyes. Do not eat, drink, or smoke in the work area. Collect waste containing selenium separately and dispose of it according to local hazardous waste regulations. Always check the supplier's Safety Data Sheet before use.
