Description générale

Pentaerythritol is acrystalline , odour less white solid. The presence of neopentane core and four terminalhydroxyl groups makes it a versatile substrate for the synthesispolyfunctionalized compounds.

Application

Pentaerythritol can be used as a starting material to prepare four armed polyurethane prepolymers, which are applicable in the synthesis of UV cured polyurethane dispersions.

It can be used as an additive in the preparation of flame retardant polymers.

It can also be used as a precursor to synthesize polyethylene glycol/4,4′-diphenylmethane diisocyanate/pentaerythritol copolymer which is applicable as heat storage material.

Synthesis of Bio-Based Poly(Butylene Adipate-co-Butylene Itaconate) Copolyesters with Pentaerythritol: A Thermal, Mechanical, Rheological, and Molecular Dynamics Simulation Study.

Chin-Wen Chen et al.

Polymers, 12(9) (2020-09-10)

Bio-based unsaturated poly(butylene adipate-co-butylene itaconate) (PBABI) aliphatic copolyesters were synthesized with pentaerythritol (PE) as a modifier, observing the melting point, crystallization, and glass transition temperatures were decreased from 59.5 to 19.5 °C and 28.2 to -9.1 °C as an increase

Efficient siRNA delivery using a polyamidoamine dendrimer with a modified pentaerythritol core.

Yue Zhang et al.

Pharmaceutical research, 29(6), 1627-1636 (2012-01-26)

Delivery of siRNA into cells remains a critical challenge. Our lab has shown a novel polyamidoamine (PAMAM) dendrimer with modified pentaerythritol derivative core (PD dendrimer) to exhibit high plasmid DNA transfection efficiency and low cytotoxicity. Here, we evaluate PD dendrimer

Polyamidoamine dendrimers with a modified Pentaerythritol core having high efficiency and low cytotoxicity as gene carriers.

Yanming Wang et al.

Biomacromolecules, 10(3), 617-622 (2009-02-14)

Polyamidoamine (PAMAM) dendrimers represent one of the most efficient polymeric gene carriers. This study describes a new family of PAMAM dendrimers that can be synthesized using a Pentaerythritol derivative (PD) as a core that possesses 12 branches. This new approach

Pharmaceutical analysis of synthetic lipid A-based vaccine adjuvants in poly (D,L-lactic-co-glycolic acid) nanoparticle formulations.

Samar Hamdy et al.

Journal of pharmaceutical and biomedical analysis, 44(4), 914-923 (2007-06-26)

The present study had two main objectives. First, was to compare the immune stimulatory effect of two synthetic lipid A analogues (7-acyl lipid A and pentaerythritol-based lipid A (PET lipid A)) on maturation/stimulation of bone marrow derived dendritic cells (DCs).

Fucosylated pentaerythrityl phosphodiester oligomers (PePOs): automated synthesis of DNA-based glycoclusters and binding to Pseudomonas aeruginosa lectin (PA-IIL).

François Morvan et al.

Bioconjugate chemistry, 18(5), 1637-1643 (2007-07-31)

The synthesis of propargylated pentaerythrityl phosphodiester oligomers (PePOs) was achieved using a DNA synthesizer with a bis-propargylated pentaerythritol-based phosphoramidite. An azido fucose derivative was reacted under "click" chemistry conditions activated by microwaves to construct a series of glycosylated PePOs bearing
