Description
Sodium dihydrogen citrate, also known as mono sodium citrate, is an acid salt with the chemical formula NaH2C6H5O7, or C3H4OH(COOH)2COONa. It is a white crystalline powder and is one of the three citric acid salts. Sodium dihydrogen citrate is a relatively strong sequestrant due to its two remaining open spots on the citrate anion. It is commonly used to prevent platelet clumping in blood samples and has various applications in different industries.

Preparation
Monosodium citrate can be prepared by the direct reaction of sodium carbonate or bicarbonate with citric acid: NaHCO3(s) + C6H8O7 (aq) → NaC6H7O7 (aq) + CO2 (g) + H2O (l).
Flammability and Explosibility
Nonflammable
Check Digit Verification of cas no
The CAS Registry Mumber 18996-35-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,9,9 and 6 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 18996-35:
(7*1)+(6*8)+(5*9)+(4*9)+(3*6)+(2*3)+(1*5)=165
165 % 10 = 5
So 18996-35-5 is a valid CAS Registry Number.
