The term "r-hydroxy-" refers to a chemical structure where a hydroxyl group (-OH) is attached to a carbon atom in a specific position, denoted by "r". This prefix is commonly used in organic chemistry to describe the position of the hydroxyl group on a carbon chain. For instance, in a molecule like 2-hydroxypropanoic acid, the "2" indicates that the hydroxyl group is attached to the second carbon atom in the chain. The presence of a hydroxyl group can significantly influence a compound's properties, such as its reactivity, solubility, and ability to form hydrogen bonds. These "r-hydroxy-" compounds are found in various natural products, pharmaceuticals, and industrial chemicals, playing crucial roles in their biological activities and applications.

3441-73-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3441-73-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,4 and 1 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 3441-73:
(6*3)+(5*4)+(4*4)+(3*1)+(2*7)+(1*3)=74
74 % 10 = 4
So 3441-73-4 is a valid CAS Registry Number.

Search for long-lived 1,3-carbodications and preparation of the persistent 1,1,3,3-tetracyclopropyl-1,3-propanediyl dication

Several substituted versions of 1,3-propanediol were ionized under a variety of superacidic conditions, and the product carbocations and carboxonium species were characterized by 13C NMR spectroscopy at low temperatures. 1,1,3-Triphenyl-1,3-pro

Oxonium Ions. Solvation by Single Acetonitrile Molecules in the Gas Phase and by Bulk Solvents

Bromilow, J.,Abboud, J. L. M.,Lebrilla, C. B.,Taft, R. W.,Scorrano, G.,Lucchini V.

, p. 5448 - 5453 (2007/10/02)

The standard free energy of formation of gaseous complexes between monoprotonic oxonium ions and acetonitrile have been obtained by using the ion cyclotron resonance equilibrium constant method for exchange of acetonitrile between the ions.The results show that the "solvation" by a single molecule of acetonitrile in the gas phase reproduces the important diverse effects of molecular structure on oxonium ion solvation by bulk water.It is estimated from the present results that the effects of solvation by bulk water are only about three times as great as the corresponding effects of "solvation" by a single water molecule in the gas phase.Internal charge delocalization from the protonic site of the oxonium ions may be reversed by differential solvation, both with single H-bonding molecules in the gas phase and with bulk solvent.Further evidence for the site of preffered protonation of esters and amides is provided.
