Product Overview

Ammonium Carbonate AR/ACS (CAS No. 506-87-6) is a volatile ammoniacal carbonate reagent conventionally represented as ammonium carbonate. Commercial material of this identity commonly contains ammonium bicarbonate and ammonium carbamate in variable proportions, producing ammonium and carbonate-containing species when dissolved in water. This compositional character provides useful alkaline and precipitating behaviour while allowing the reagent to decompose without introducing a metallic counterion.

The AR/ACS grade is intended for analytical reagent preparation, classical qualitative analysis, quality-control testing, and research procedures requiring controlled composition and limited reagent-derived impurities. It is suitable for preparing ammoniacal carbonate media and carrying out precipitation or separation procedures involving compatible metal ions.

Typical Applications

• Preparation of ammoniacal carbonate analytical reagents
• Precipitation of calcium, strontium, and barium ions as carbonates
• Separation of alkaline-earth-metal ions in classical qualitative analysis
• Preparation and examination of selected metal carbonate precipitates
• Establishment of mildly alkaline carbonate-containing analytical media
• Routine analytical, quality-control, and inorganic chemistry procedures

Common Synonyms

• Diammonium Carbonate
• Carbonic Acid, Diammonium Salt
• Carbonic Acid, Ammonium Salt (1:2)

Storage Conditions

Store in a tightly closed container in a cool, dry, and well-ventilated location. Protect the material from heat, atmospheric moisture, and prolonged exposure to air. Reseal the container promptly after dispensing to minimise the loss of ammonia and carbon dioxide and preserve its analytical reagent quality.
