Definition
ChEBI: A citrate salt in which all three carboxy groups are deprotonated and associated with ammonium ions as counter-cations.
Agricultural Uses
Ammonium citrate is a white, granular, water-soluble
salt of ammonia and citric acid. It is used in a neutral
solution for determining the phosphorus content of
phosphate fertilizers (such as calcium hydrogen
phosphate (CaHPO4)), that are insoluble in water but
dissolve in complexing citrate solutions.
The fertilizer residue, after extraction of watersoluble
phosphorus, is re-extracted with a neutral or
strongly alkaline solution of 1 normal (1N) ammonium
citrate for a prescribed period, and the slurry filtered.
Citrate-soluble phosphorus is the phosphorus content in
the filtrate and is expressed as a percentage by weight of
the fertilizer.
The extraction of phosphate with 1N ammonium
citrate is carried out routinely for 30 minutes, first at
room temperature and then at 4O℃ For neutral
ammonium citrate solution, a temperature of 65℃ is
preferred.
Some European countries use an alkaline ammonium
citrate solution, which extracts smaller amounts of
phosphorus. Some experts consider it to be better
correlated with phosphorus uptake and plant growth.
However, most countries use a neutral normal
ammonium citrate solution for extracting citrate soluble
phosphorus.

Check Digit Verification of cas no
The CAS Registry Mumber 3458-72-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,5 and 8 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 3458-72:
(6*3)+(5*4)+(4*5)+(3*8)+(2*7)+(1*2)=98
98 % 10 = 8
So 3458-72-8 is a valid CAS Registry Number.

PROCESSES FOR PRODUCING NH4+ -OOC-R-COOH COMPOUNDS FROM FERMENTATION BROTHS CONTAINING NH4+ -OOC-R-COO-NH4+COMPOUNDS AND/OR HOOC-R-COOH COMPOUND ACIDS, AND CONVERSION OF NH4+ -OOC-R-COOH COMPOUNDS TO HOOC-R-COOH COMPOUND ACIDS

Page/Page column 31, (2011/11/13)
A process for making a NH4+ OOC-R-COOH compound from a clarified NH4+ OOC- R-COO' NH4+ compound-containing fermentation broth includes (a) distilling the broth to form an overhead that includes water and ammonia, and a liquid bottoms that includes a NH4+ OOC~R~COOH compound, at least some of a NH4+ QOC-R-COO" NH4+ compound, and at least about 20 wt% water; (b) cooling the bottoms to a temperature sufficient to cause the bottoms to separate into a NH4+ OOC-R~C00' NH4+ compound-containing liquid portion in contact with a NH4+ OOC-R-COOH compoond-containing solid portion that is substantially free of the NH4+ OOC-R-COO" NH4+compound; (c) separating the solid portion from the liquid portion; and (d) recovering the solid portion.
