Some Thermochemical Properties of Fluorinated Ethanol’s and its Radicals : CH3-xCH2FxOH,CH3CH2, Heat Capacity and Bond Dissociation Energy using Gaussian Calculations

The goal of this study is to calculate enthalpies of formation in Kcal/mol, entropy, and heat capacity in cal/mol.K using the gaussian M-062x/6-31 + g (d, p) Ab initio and density functional theory methods, as well as to include the internal rotor contribution of each molecule to the calculated values of entropy and heat capacity […]

Assessment of Isoniazid and Pyridoxine Hydrochloride in Pure and Pharmaceutical Preparations

For the simultaneous assay of pyridoxine hydrochloride and isoniazid, a new spectrophotometric approach was devised. The approach was based on a proton transfer reaction between pyridoxine hydrochloride B6 and chromeazurol S at pH = 5.7, which produced a red, water soluble compound that absorbed at 510 nm. This technique for detecting isoniazid IND was discovered […]

Visible Quantitative Methods for the Determination of Furosemide in Pure form and Pharmaceutical Formulations: A Recent Study

The goal of this research is to develop technological methods for determining furosemide in both its pure and pharmaceutical dose forms utilising spectral approaches. This study was designed and carried out to assess Furosemide in pure and pharmaceutical dose forms using visible spectrophotometry. This research was conducted from April to August 2021 at the Laboratory […]

Role of Catalysis in Sustainable Chemistry and Conservation of Environment

Sustainable chemistry is focused with the creation of products that decrease the use and manufacture of environmentally harmful hazardous chemicals. Sustainable Chemistry is based on Paul Anastas and John Werner’s 12 Principles of Green Chemistry, which were published in the 1990s and lay out a roadmap for long-term growth. The most essential of them is […]

Metformin HCL: Visible Spectrophotometric Determination in Pure and Dosage Forms

Metformin HCl is an antidiabetic medication that belongs to the biguanidine pharmacological family. Metformin HCl (MET) in pure form and pharmaceutical formulations is determined using simple and innovative visible spectrophotometric procedures. The production of coloured complexes allows for the development of selective visible spectrophotometric approaches. The method is based on the reaction between the medication […]

Study about 2-83bromo -2-deoxyglucose, 6-bromo-glucose: Two Trojan Horses for the War against Cancer? – 3-18fluoro-pyruvate as a Probe for Enhanced Expression of Monocarboxylate Transporters in Cancer

Since its discovery almost a century ago (Warburg), the times-fold increase in glycolysis in cancer has been a well-studied impact in cancer research for many years, if not decades, and it is now recognised as the most significant characteristic of cancer. As a result, some researchers have recently suggested that inhibiting glycolysis in cancer cells […]

An ab-initio Study of the Electronic and Physical Properties of RRhAl (R = La, Y)

The TBLMTO technique was used to acquire the electrical and physical characteristics of intermetallic compounds such as LaRhAl in the orthorhombic Pd2 (Mn, Pd)Ge2 type structure and YRhAl in the orthorhombic TiNiSi type structure under decreased volume pressure. These compounds’ equilibrium lattice parameters and bulk modulus are determined and compared to the literature. For equilibrium […]

Hydrophobic Coating Based on Modified Low Molecular Weight Polyethylene and Atactic Polypropylene

Polyethylene and polypropylene manufacture produce low molecular weight polyethylene and atactic polypropylene, which are multi-tonnage by-products. One of the most essential environmental problems is to solve the problem of their practical application or disposal. The goal of this paper is to provide a theoretical rationale and recommendations for the practical application of low-molecular-weight polyethylene and […]

Effect of Sodium Chloride Salts on Benzoic Acid Solubility and Dissociation into Water at 298 K

This study looked at the influence of sodium chloride (NaCl) salt concentration on benzoic acid (C6H5COOH) solubility and dissociation in water at 298 K temperature. Titrimetrically against a 0.05 M sodium hydroxide (NaOH) solution, the solubility of benzoic acid in water and their dissociation values in six ranges of 0.00, 0.05, 0.10, 0.30, 0.40, and […]

Manganese(III) Complexes with Decolourization Ability

From Mn(gly)2Cl, Mn(gly)2Br, Mn(gly)2N3, and Mn(gly)2NCS, some new mixed ligand complexes of Mn(III) with glycine ligand have been synthesised, namely [Mn(gly)2Cl(en)], [Mn(gly)2Br(en)], [Mn(gly)2N3(en) UV/visible, FT-IR, and mass spectrometry were used to characterise these complexes. All of these unique compounds have distorted octahedral geometry, according to the spectroscopic data. The maximum values for these complexes (5T2g […]
