English description（英文原文，共 1181 字符）
Product Name:Magnesium mono(4-nitrobenzyl) malonate
English Name:Magnesium mono(4-nitrobenzyl) malonate
CAS No.:83972-01-4
Aliases:Magnesium 3-((4-nitrobenzyl)oxy)-3-oxopropanoate, p-Nitrobenzyl malonate magnesium salt, Magnesium mono(p-nitrobenzyl) malonate
Molecular Formula:C20H16MgN2O12
Physical Properties:White to light yellow crystalline powder. Stable in dry air; sparingly soluble in water; soluble in polar solvents such as N,N-dimethylformamide (DMF) and dimethyl sulfoxide (DMSO); decomposes in strong acids to give p-nitrobenzyl hydrogen malonate and magnesium salts.
Uses:Used as an intermediate in organic synthesis. It reacts with acyl chlorides or active esters to introduce a mono-malonate acyl group, affording β-keto esters and substituted carboxylic acid derivatives. The p-nitrobenzyl protecting group can be removed by catalytic hydrogenolysis, making it useful in the synthesis of carbapenem and β-lactam pharmaceuticals and fine chemicals.
Technical Specifications:
Assay (HPLC) ≥98.0%
Appearance: white to light yellow crystalline powder
Loss on drying ≤0.5%
Heavy metals ≤10 ppm
Solubility: soluble in DMF and DMSO, sparingly soluble in water
