Applications

Sodium telluride is used as a semiconductor, as a reducing agent and to prepare organic tellurium compounds. It is used in the reduction of aromatic carbonyl compounds to alcohols. It is also used in the preparation of pyrrolo[2,3-d]pyrimidines (7-deaza-9H-purines) from aromatic nitriles. It is used to prepare nanocrystalline zinc telluride.

Notes

Air and moisture sensitive. Hygroscopic in nature. It oxidizes in air to from polytellurides. Keep the container tightly closed. Incompatible with acid, oxidizing agents and water.

GHS Hazard and Precautionary Statements

Hazard Statements: H261-H302-H312-H315-H319-H332

In contact with water releases flammable gas. Harmful if swallowed. Harmful in contact with skin. Causes skin irritation. Causes serious eye irritation. Harmful if inhaled.

Precautionary Statements: P223-P231+P232-P261-P264b-P270-P271-P280-P301+P312-P302+P352-P304+P340-P305+P351+P338-P312-P330-P332+P313-P335+P334-P337+P313-P362-P370+P378q-P501c

Keep away from any possible contact with water, because of violent reaction and possible flash fire. Handle under inert gas. Protect from moisture. Avoid breathing dust/fume/gas/mist/vapours/spray. Wash face, hands and any exposed skin thoroughly after handling Do not eat, drink or smoke when using this product. Use only outdoors or in a well-ventilated area. Wear protective gloves/protective clothing/eye protection/face protection. IF SWALLOWED: Call a POISON CENTER or doctor/physician if you feel unwell. IF ON SKIN: Wash with plenty of soap and water. IF INHALED: Remove to fresh air and keep at rest in a position comfortable for breathing. IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing. Rinse mouth. If skin irritation occurs: Get medical advice/attention. Brush off loose particles from skin. Immerse in cool water/wrap in wet bandages. If eye irritation persists: Take off contaminated clothing and wash before reuse. In case of fire: Use CO2, dry chemical, or foam Dispose of contents/ container to an approved waste disposal plant
