Ammonia

Ammonia is an azane that consists of a single nitrogen atom covelently bonded to three hydrogen atoms. It has a role as a NMR chemical shift reference compound, a metabolite, a neurotoxin, a nucleophilic reagent, a mouse metabolite, an EC 3.5.1.4 (amidase) inhibitor and a refrigerant. It is a gas molecular entity, an azane and a mononuclear parent hydride. It is a conjugate base of an ammonium. It is a conjugate acid of an azanide. — ChEBI

Verification workflow and record completeness

Before using this result in a compliance decision

  1. Confirm that “Ammonia CAS No 7664-41-7/1336-21-6” and every CAS/EC identifier refer to the material in your supplier specification.
  2. Search all ACD annexes by name and identifiers.
  3. Apply product type, maximum level and warning conditions.
  4. Confirm the target member state's adoption and transition date.
  5. Complete the local notification and responsible-company requirements.
  6. Document the source version and recheck the regulator before manufacture, notification or market placement.

Questions this page answers

This substance is not unrestricted: cosmetic use is subject to the conditions in the cited official record. Check product type, body area, concentration, purity and warning requirements before deciding whether a formulation is compliant.

If this row does not reproduce conditions, open the cited official detail because omission does not mean unrestricted use. Regional annex coverage does not replace member-state implementation dates, notifications or national deviations.

The record cites ASEAN Annex III, reference 4, source version 2026-1. Open the official source.

No. CAS helps resolve identity, but jurisdictions can classify the same substance differently and can apply different product scopes, limits, warnings and transition dates.
