Request SDS →Ammonium citrate, dibasic (CAS 3012-65-5, C6H14N2O7) is the diammonium salt of citric acid. It is used as a buffering agent and a chelating/sequestering agent, as an analytical reagent for phosphate determination in fertilizers, and in rustproofing and cotton/textile printing.
Frequently Asked Questions
What is ammonium citrate dibasic used for?
Ammonium citrate dibasic (the diammonium salt of citric acid) is used as a pH-buffering agent, as a chelating/sequestering agent for metal ions in industrial and cleaning systems, as an analytical reagent for phosphate determination in fertilizer analysis, in rustproofing/corrosion-protection treatments, and as a cotton-printing auxiliary. The ACS grade meets American Chemical Society reagent specifications for analytical work.
What is the chemical formula and CAS number of ammonium citrate dibasic?
Ammonium citrate dibasic is C6H14N2O7 (CAS 3012-65-5), the diammonium salt of citric acid. It is classified under HS code 2918.15 (salts and esters of citric acid). Identity and assay are confirmed on the product Certificate of Analysis.
What is the difference between ammonium citrate dibasic and tribasic?
Dibasic (diammonium) citrate carries two ammonium ions per citrate, while tribasic (triammonium) citrate carries three, giving the tribasic salt a higher pH in solution. This product is the dibasic ACS grade. Confirm the salt form and intended buffering range against your application requirements.
What does ACS grade mean for ammonium citrate dibasic?
ACS grade means the material meets the purity specifications set by the American Chemical Society, making it suitable for analytical reagent use such as phosphate determination in fertilizer testing. The CoA documents assay and impurity limits against those specifications. Higher-purity reagent grade typically commands a premium over technical material.
How is bulk ammonium citrate dibasic packaged and shipped?
It is supplied in industrial packaging such as bags, drums, and bulk to manufacturers and labs. It carries UN 3077 (environmentally hazardous substance, solid, n.o.s.) for transport classification, so confirm DOT/IMDG documentation with your shipment. Request a bulk quote with SDS and CoA for your volume.
