Azide

Description

Sodium azide is an inhbitor of cytochrome c oxidase (COX, CcO).

Abbreviation: Azd

Reference: MiPNet03.02

Application in HRR

Azd: Azide (Sodum azide; NaN₃), Sigma-Aldrich: S2002, store at RT, CAS: 26628-22-8, M = 65.01 g·mol^-1

Hazard statements: H300, H310, H330, H373, H410; fatal if swallowed, fatal in contact with skin, fatal if inhaled, may cause damage to organs through prolonged or repeated exposure (brain), very toxic to aquatic life with long-lasting effects

2021-03: Preparation instructions were updated to take the volume of the solute into account (see Volume of the solute). The concentrations prepared following the former instructions (see Discussion section) are sufficiently high for SUIT protocol titrations.

Preparation of 4 M storage and stock solution (1 mL, dissolved in H₂O) for 2-mL O2k-chamber:

1. Weigh 260 mg of sodium azide.
2. Dissolve in 900 µL H₂0.
3. Divide into 0.5 mL portions.
4. Store at -20 °C.

• Titration volume (2-mL O2k-chamber): ≥50 µL using a 100 µL Hamilton syringe.
• Final concentration: ≥100 mM.

Preparation of 2 M stock solution (dissolved in H₂O) for 0.5-mL O2k-chamber:

1. Take 400 µL of the 4 M stock solution.
2. Add 400 µL H₂O.
