921-53-9 Usage
Description
Potassium tartrate, also known as dipotassium tartrate or argol, is the potassium salt of tartaric acid with the chemical formula K2C4H4O6. It is often confused with potassium bitartrate, also known as cream of tartar. As a food additive, it shares the E number E336 with potassium bitartrate.
Uses
Used in Chemical Industry:
Potassium tartrate is used as a raw material for the manufacture of potassium salts and as a laboratory reagent.
Used in Pharmaceutical Industry:
Potassium tartrate is used as a cathartic, which is a substance that stimulates bowel movements and helps relieve constipation.
Used in Food Industry:
Potassium tartrate is used as an acidulant in chemical leavening to release carbon dioxide, which produces the loaf volume in baked goods. It functions as a taste regulator in sugar icing and helps in controlled crystallization of toffees and fondants by regulating the inversion of sucrose. It is used in various food products such as baked goods, crackers, candy, and puddings.
Used in Food Additive Industry:
As a food additive, potassium tartrate shares the E number E336 with potassium bitartrate, which allows it to be used in various food products for specific purposes.
Preparation
Potassium tartrate is produced by the reaction of tartaric acid with potassium sodium tartrate (rochelle salt), and potassium sulfate, followed by filtration, purification, precipitation and drying.

Check Digit Verification of cas no
The CAS Registry Mumber 921-53-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,2 and 1 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 921-53:
(5*9)+(4*2)+(3*1)+(2*5)+(1*3)=69
69 % 10 = 9
So 921-53-9 is a valid CAS Registry Number.
