39469-81-3 Usage

Uses

Used in the Wine Industry:
Metatartaric acid is used as a stabilizing agent to prevent the formation of tartrate crystals in bottled wines. It functions by binding to potassium and calcium ions, inhibiting their combination with tartaric acid and the subsequent formation of crystals. This contributes to the improved clarity and stability of the wine.
Used as a Chelating Agent in Industrial Processes:
Metatartaric acid serves as a chelating agent in various industrial applications, where it helps to bind and remove metal ions, enhancing the efficiency of processes and preventing unwanted reactions.
Used as a Food Additive:
In the food industry, metatartaric acid is utilized as an additive to improve the stability and appearance of certain products. Its chelating properties can help maintain the quality and extend the shelf life of food items by preventing unwanted chemical interactions.

Check Digit Verification of cas no

The CAS Registry Mumber 39469-81-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,4,6 and 9 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 39469-81:
(7*3)+(6*9)+(5*4)+(4*6)+(3*9)+(2*8)+(1*1)=163
163 % 10 = 3
So 39469-81-3 is a valid CAS Registry Number.
