Key Properties

• Strongly alkaline (high pH, typically >11)

• Maintains constant ionic strength

• Prevents formation of volatile hydrogen cyanide (HCN)

• Improves accuracy and stability of cyanide ISE readings

• Stable under proper storage conditions

Uses

• Cyanide determination using ion-selective electrodes (ISE)

• Environmental and wastewater analysis

• Industrial process monitoring

• Analytical chemistry and quality control laboratories

Storage

• Store in tightly closed, alkali-resistant containers

• Keep in a cool, dry place away from acids

• Protect from contamination

Safety & Handling (SDS Summary)
⚠️ High-risk reagent when used with cyanide samples

• Strongly alkaline; causes severe skin and eye irritation

• Prevent contact with acids (acidification can release toxic HCN gas)

• Wear full PPE: gloves, lab coat, goggles, face shield if needed

• Use only in a well-ventilated area or fume hood

• Dispose of as hazardous chemical waste according to regulations
