13042-39-2 Usage

Uses

1,4:3,6-Dianhydro-2-O-acetyl-D-glucitol is a useful reagent in the practical enzymic synthesis of isosorbide-2-acetate.

Check Digit Verification of cas no

The CAS Registry Mumber 13042-39-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,0,4 and 2 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 13042-39:
(7*1)+(6*3)+(5*0)+(4*4)+(3*2)+(2*3)+(1*9)=62
62 % 10 = 2
So 13042-39-2 is a valid CAS Registry Number.

Volatile short-chain amphiphiles derived from isosorbide: Hydrotropic properties of esters vs. ethers

Lavergne, Aurelie,Moity, Laurianne,Molinier, Valerie,Aubry, Jean-Marie

, p. 5997 - 6007 (2013)

Two series of short-chain isosorbide monoalkanoates, differing from the free hydroxyl position, were synthesized and evaluated as volatile non-ionic hydrotropes, also known as solvo-surfactants . Their aqueous solubilities, solubilizing efficiencies and volatilities were evaluated and compared to the corresponding 5-O-alkylisosorbides. Whatever the acylation position (5-O- or 2-O-), isosorbide monoalkanoates are poorly water-soluble for acyl chains longer than four carbons, whereas 5-O-alkylisosorbides are completely miscible with water up to a pentyl chain, which seems to indicate that an ether link brings more hydrophilicity than an ester bond for these types of molecules. The shorter isosorbide monoalkanoates are completely miscible with water and the butanoates are particularly efficient in terms of aqueous solubilization of hydrophobic compounds. In addition, all hydrotropes exhibit some volatility albeit being non-VOC and contrarily to their ethers homologues, isosorbide alkanoates are easily hydrolysed in basic medium, which suggests a good biodegradability.

Method for synthesizing isohexitol ester

-

Paragraph 0010; 0043-0050; 0055-0056, (2021/05/05)

The invention discloses a method for synthesizing isohexitol ester, which is characterized in that a material containing hexitol and an esterifying agent is contacted with a solid acid catalyst in the presence of an aprotic solvent, and the isohexitol ester is obtained through one-pot one-step reaction. The method is especially suitable for the reaction of directly synthesizing the isohexitol ester, especially isosorbide ester, from hexitol, especially sorbitol, the total yield of the obtained isohexitol ester is 80% or above, and the yield of the isosorbide dicarboxylate reaches 60% or above.

Selective Methylmagnesium Chloride Mediated Acetylations of Isosorbide: A Route to Powerful Nitric Oxide Donor Furoxans

Isosorbide was functionalized with furoxan for the first time to give adducts that release nitric oxide up to 7.5 times faster than the commercial vasodilator, isosorbide-5-mononitrate (Is5N). The synthesis was facilitated by MeMgCl-mediated selective acetylation of isosorbide or selective deacetylation of isosorbide-2,5-diacetate, which was rationalized in terms of a more stable 5-alkoxide magnesium salt using DFT. Isosorbide-furoxans are safer to handle than Is5N due to greater thermal stability.
