Sodium azide, a potentially lethal chemical, is used as a preservative agent in the extraction vial of many rapid COVID-19 tests kits. The Centers for Disease Control and Prevention (CDC) defines ...

In particular, in order to study the photolysis of barium azide by electron spin resonance, crystals with a minimum size of about 5 × 2 × 1 mm are required.

Sodium azide, often used as a preservative, is a liquid reagent in several of the COVID-19 test kits, she said. Ingesting it can cause low blood pressure, which can result in dizziness, headaches ...

exposed to bright light, or even left undisturbed on a glass plate. Like all azides, it reacts with water to emit explosive, highly toxic hydrogen azide. Azidoazide azide has been called “ the most ...

However, conventional synthesis methods for azide compounds have severe limitations. To this end, a team of researchers has developed an efficient method to prepare chemical intermediates having ...

The liquid in some rapid at-home COVID-19 tests contains a small amount of the toxic chemical sodium azide, but they are safe when used properly.
