Chemical Properties

fine powder

Uses

Malonic Acid-d4 is the isotope labelled analog of Malonic Acid (M158005); a small bioactive molecule that can be used in various reactions. It is the classic example of a competitive inhibitor which acts against succinate dehydrogenase (complex II) in the respiratory electron transport chain.

Check Digit Verification of cas no

The CAS Registry Mumber 813-56-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,1 and 3 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 813-56:
(5*8)+(4*1)+(3*3)+(2*5)+(1*6)=69
69 % 10 = 9
So 813-56-9 is a valid CAS Registry Number.

ESTIMATION OF MALONIC ACID AND METHYLMALONIC ACID ENOLIZATION RATE CONSTANTS BY AN ISOTOPIC-EXCHANGE REACTION USING 1H NMR SPECTROSCOPY

Hansen, Eddy W.,Ruoff, Peter

, p. 2641 - 2645 (1988)

In the oscillatory Belousov-Zhabotinsky (BZ) reaction, bromination of the organic substrate is an important component process.Because bromination of the organic substrate in the BZ reaction occurs via an enolization mechanism, which generally is considered to be rate determining, the enolization rate constants are important parameters.In this paper, we erport enolization rate constants of malonic and methylmalonic acid in 1 M sulfuric acid by following with 1H NMR spectroscopy the isotopic substitution of enol-exchangeable hydrogen atoms by deuterium.We find for the first enolization step of malonic acid a rate constant of (1.066+/-0.003)x1E-3 s-1 and for the second enolization step a rate constant value of (4.2+/0.2)x1E-4 s-1.The corresponding value for methylmalonic acid is (5.7+/-0.1)x1E-5 s-1.While earlier literature data for malonic acid are difficult to compare with our present results, the determined enolization rate constant for methylmalonic acid is in excellent agreement with two other experimental determinations performed in 1 M sulfuric acid.When the sulfuric acid activity is taken into account, then methylmalonic acid enolization rates can be extrapolated to other sulfuric acid concentrations.
