METIL-FORMAMIDA NA CRIOPRESERVAÇÃO DE SÊMEN OVINO

Ciência Animal Brasileira, 2013
The aim of this study was to evaluate the efficacy of methyl-formamide in ram semen cryopreservation. The semen pool used in this experiment was obtained by artificial vagina collection from four mixed breed Santa Inês rams, around four years of age ...

Two-Dimensional Lattices with Lanthanoids, Anilato Ligands and Formamide

Crystals, 2023
Here, we illustrate the use of formamide (fma) and anilato-type ligands to build two-dimensional lattices with lanthanoids. Thus, we describe the synthesis and crystal structure of four lattices formulated as [Ln2(C6O4X2)3(fma)6]·6fma with Ln/X = La/Cl ...

A Novel Phosphorescent Iridium(III) Complex Bearing Formamide for Quantitative Fluorine Anion Detection

Crystals, 2021
Fluorine anion plays a critical role for human health, especially for the teeth and the skeletal system, and a deficiency or excess of fluorine anion will result in various diseases. Thus, the accurate and timely detection of fluorine content is of great

N-(2,3,5,6-Tetrafluoropyridin-4-yl)formamide

IUCrData, 2022
The title compound, C6H2F4N2O, displays amide bond lengths of 1.218 (3) Å and 1.366 (3) Å for the C=O and C—N bonds, respectively. The Cp—N—C—O (p = pyridine) torsion angle of 179.0 (2)° indicates an anti-conformation for the grouping.

Interfacial Pockels Effect of Solvents with a Larger Static Dielectric Constant than Water and an Ionic Liquid on the Surface of a Transparent Oxide Electrode

Applied Sciences, 2022
The optical Pockels effect is a change in the refractive index proportional to an applied electric field. As a typical example of the interfacial Pockels effect occurring at interfaces where the spatial inversion symmetry is broken, it is known that ...

Prebiotic Route to Thymine from Formamide—A Combined Experimental–Theoretical Study

Molecules, 2021
Synthesis of RNA nucleobases from formamide is one of the recurring topics of prebiotic chemistry research. Earlier reports suggest that thymine, the substitute for uracil in DNA, may also be synthesized from formamide in the presence of catalysts ...

An Efficient Method for the Preparation of N-Formamides using Propylphosphonic Anhydride (T3P®)

SynOpen, 2018
The synthesis of N-formamides from aromatic amines and formic acid using propylphosphonic anhydride (T3P®) as a green coupling reagent is described. By using this method, aryl, heteroaryl and fluorinated aryl-containing formamides were synthesized in ...
