Frequently asked questions

What is sodium azide 10% solution in water commonly used for?

This solution is primarily used as a reagent in analytical chemistry, for example in the azide modification of the Winkler dissolved-oxygen titration, where it removes nitrite interference, and as a precursor for azide chemistry in organic synthesis.

What is the chemical formula and molecular weight of sodium azide?

The formula is N₃Na (sodium azide), and the molecular weight is 65.01 g/mol (anhydrous). The 10% solution adjusts the effective concentration per volume.

How should sodium azide 10% solution be stored?

Store at ambient temperature in a cool, dry place, away from heat, sparks, or open flames. Use airtight containers to prevent decomposition.

What purity grades or forms of sodium azide solution does Molekula offer?

Molekula supplies this as a 10% w/w aqueous solution (analytical grade). Higher concentrations or solid forms are available upon request—confirm specifications during ordering.

Can Molekula supply sodium azide solution in bulk quantities?

Yes, bulk quantities are available—contact our sales team for custom packaging options (e.g., drums, IBCs) and lead times, especially for orders exceeding 5 kg.

What documentation is provided with a sodium azide solution order?

Each order includes a Certificate of Analysis (CoA), Material Safety Data Sheet (MSDS/SDS), and batch-specific documentation for traceability. Hazard labels are affixed to packaging.
