• CAT Number: R023593
• CAS Number: 3458-72-8
• Molecular Formula: C6H17N3O7
• Molecular Weight: 243.22
• Purity: ≥95%

Citric acid triammonium (Triammonium citrate) is formed by Citric acid (HY-N1428) reacting with ammonia in a molar ratio of 1:3. Citric acid triammonium can be used as the carbon source to prepare carbon quantum dots (CDs). Citric acid triammonium with higher nitrogen components might promote the nitrogen-based functional groups in CDs, leading to a more efficient emission-color tunability[1][2].
