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.

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.

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 ...

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 ...
