Usage

General Description

Phosphonic acid, monomethyl ester, sodium salt is a chemical compound that is a salt of monomethyl phosphonic acid and sodium. It is commonly used as a sequestering agent in various industrial and household applications. Phosphonic acid, monomethyl ester, sodium salt is a strong chelating agent, which means it can bind to metal ions and remove them from solution, making it useful in cleaning products and industrial processes. It is also used as a scale and corrosion inhibitor in water treatment. Additionally, it is used in agricultural applications as a herbicide and a plant growth regulator. Overall, phosphonic acid, monomethyl ester, sodium salt has a wide range of uses due to its chelating and inhibitory properties.

Prodrugs of Phosphonoformate: Products, Kinetics and Mechanisms of Hydrolysis of Dibenzyl (Methoxycarbonyl)phosphonate

Dibenzyl (methoxycarbonyl)phosphonate (1) has been prepared by the reaction of benzyl alcohol with (methoxycarbonyl)phosphonic dichloride.The hydrolysis of 1 proceeded rapidly, with a half-life of 60 min at 36.4 deg C and pH 7.4, by two main pathways.The dominant pathway (k1, 6.56 * 10-3 min-1) yielded the diester, benzyl (methoxycarbonyl)phosphonate (2) and benzyl alcohol (3), with P-O cleavage.The second (k2, 3.55 * 10-3 min-1) gave dibenzyl phosphite (4), possibly arising from the hydrolysis of the carboxyl ester followed by decarboxylation.Benzyl phosphite (5) was also observed, which arises from the hydrolysis of 4 with P-O cleavage (k5, 9.04 * 10-4 min-1).Other products formed in small amounts were, benzyl (benzyloxycarbonyl)phosphonate (6) (k3, 3.59 * 10-4 min-1) and dibenzyl phosphate (7) (k4, 4.24 * 10-4 min-1).The rapid and complicated hydrolysis of 1, involving four competitive reactions, two of which involve C-P bond cleavage, suggests that triesters of phosphonoformate are unlikely to be suitable prodrug forms.

Reactions with Aziridines (Aziranes), 29. N-Acylated or N-Sulfonated Esters of 2-Aminoethylphosphonic Acid by Mean of Base Catalyzed Aminoethylation of Diesters of Phosphoric Acid with Activated Aziridines.

The sodium salts 2 of diesters of phosphoric acid 1 are amidoethylated at phosphorus with N-acylaziridines 3 or N-sulfonylaziridines 13 under proper reaction conditions at room temperature.In this manner a broad variation of N-acylated or N-sulfonated esters of 2-aminoethylphosphonic acids (5a-u, 15a-i) are obtained, mostly in good yields. 2-Methylated 2-aminoethylphosphonic esters are formed selectively in two cases by reaction of 2-methylated activated aziridines.
