Potassium Iodide ANTI-RAD — store notes on a light-sensitive salt

Description

Potassium iodide (CAS 7681-11-0, formula KI, molar mass 166.00 g/mol, EC number 231-659-4) is an inorganic salt handled in the reagent store as a hygroscopic, light-sensitive solid. The notes below cover identity, shelf conditions, segregation, movement and records. Zobacz również odczynnik laboratoryjny tej klasy: Aniracetam ≥ 99%. Czysta substancja chemiczna bez .

Identity of the lot

The material is identified by registry number, never by the trade designation printed on the carton.

• CAS registry number 7681-11-0 and EC number 231-659-4 read from the primary label.
• Formula KI and molar mass 166.00 g/mol used to recalculate the declared content.
• Lot number and packaging date transcribed onto the internal stock card.
• Certificate of analysis filed together with the safety data sheet.

Why light and moisture govern the shelf

Iodide is slowly oxidised to iodine on contact with air and light, so a white crystalline solid may acquire a yellow tint.

• Amber glass or an opaque secondary container for every opened package.
• Closed cabinet away from windows and from luminaire heat.
• Desiccated space wherever the lot specification calls for it.
• Container reclosed immediately after each withdrawal.
• Discolouration logged as a storage signal, then verified analytically.

Segregation on the shelf

Iodides are kept apart from oxidising agents and from acids.

• Separate zone from chlorates, nitrates, peroxides and permanganates.
• Distance from strong acids that liberate hydrogen iodide.
• Shelving protected against spillage, because iodine stains are persistent.
• Compatibility group written on the shelf label, not only in the register.

Working portions

A working portion is drawn once and labelled at the moment it leaves the primary container.

• Secondary vessel marked with substance name, lot number and date of transfer.
• Weighing carried out away from draughts and from open acid vessels.
• Residues returned to the open-stock zone or booked into laboratory waste.
• Spatulas dedicated to the salt to avoid carry-over between containers.

Transport and dispatch

The salt travels in tightly closed primary packaging inside a rigid outer box.

• Absorbent filler occupying the free space around the container.
• Transport marking taken from the classification in the safety data sheet.
• Copies of certificate and data sheet attached to the shipping file.
• Acceptance at destination repeating the complete goods-in check.

Records and periodic inspection

Stock discipline rests on a written trail rather than on memory.

• Withdrawal log holding date, lot number, mass taken and mass remaining.
• Periodic inspection for caking, colour change and seal damage.
• Doubtful lots re-checked by titration against a standard solution.
• Closing entry on the stock card when a lot leaves circulation.
