Overview of Thin Layer Chromatography (TLC)
In 1901, Russian botanist Mikhail Tswett used petroleum ether to separate plant pigments for the first time and created classical chromatography. As a separation technology, chromatography has been continuously developed in the past 100 years.

Overview of Ammonium Sulfate
Ammonium sulfate is an inorganic salt with the chemical formula (NH₄)₂SO₄. It's a white to yellowish-gray crystalline solid that's soluble in water. A common use is as a fertilizer for alkaline soils, as it provides nitrogen and sulfur, and also helps lower the soil pH.

Alkanes Vs Alkenes Vs Alkynes
Organic substances formed by the two elements of carbon and hydrogen are called hydrocarbons. According to the bonding mode between carbon atoms in the molecule, they can be divided into saturated hydrocarbons and unsaturated hydrocarbons.

What Makes Fluvastatin Unique? Pharmacological Superiority in High-Risk Populations
Fluvastatin is a synthetic lipid-lowering agent that belongs to the statin class, specifically acting as a 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitor.

Comprehensive Scientific Overview of Peptides: Extraction Techniques and Applications in Biomedicine and Food Industries
Peptides consist of short amino acid chains that connect through peptide bonds (-CO-NH-) and generally contain between 2 and 50 amino acids.

Fluorescent Tracers: Precision Tools for Advanced Imaging, Diagnostics, and Molecular Tracking
Fluorescent tracers are fluorescent dyes or molecules that emit light when exposed to ultraviolet (UV) or visible light.

Comprehensive Overview of Cyanine Fluorophores: Structure, Applications, and Innovations in Fluorescent Labeling
Cyanine fluorophores are a class of synthetic dyes characterized by a polymethine chain flanked by two nitrogen-containing heterocycles, typically indoles, benzothiazoles, or quinolines.

Advancing Optoelectronics and Bioimaging with InP/ZnS Quantum Dots
Indium phosphide/zinc sulfide (InP/ZnS) quantum dots (QDs) are a class of semiconductor nanocrystals that exhibit exceptional optical properties due to their quantum confinement effects.

Advanced Guide to Azide PEG: Key Properties, Reactions, and Biomedical Integration
Azide PEG, or azido-functionalized polyethylene glycol, is a class of hydrophilic polymers with azide (-N3) groups covalently bound to PEG chain termini or side chains.

Table of Strength of Conjugate Acid and Base
There is a definite relationship between the dissociation constants Ka and Kb of the conjugate acid-base pair. KW is called the ion product of water.

Phase Transfer Catalysis
Many inorganic salts are easily soluble in water, insoluble or difficult to dissolve in organic solvents. On the contrary, most organic substances are soluble in organic solvents but difficult to dissolve in water.

Nucleosides vs Nucleotides
Both nucleotides and nucleosides are important molecules in living organisms. They are composed of purine or pyrimidine bases, sugars, and phosphates. However, there are some key differences between them.

Introduction to Chromatography-Mass Spectrometry
Mass spectrometry has the characteristics of high sensitivity and strong qualitative ability, but it is difficult to identify and quantify multi-component complex mixtures; chromatography has the characteristics of efficient separation of multi-component mixtures and simple quantitative analysis, but its qualitative ability is poor.

The Safety, Indications, and Future Prospects of D-Pantethine
D-pantethine is the dimerized form of pantothenic acid (vitamin B5), consisting of two pantothenic acid molecules linked by a disulfide bond.

Tetrachloroveratrole: A Key Chemical in the Papermaking Industry and Beyond
Tetrachloroveratrole is a chlorinated derivative of guaiacol, specifically a product of bacterial O-methylation of trichloroguaiacol and tetrachloroguaiacol.

Hernandulcin: A Rare Natural Sweetener with Promising Biological Activity
Hernandulcin exists naturally as a sesquiterpene-derived secondary terpene, which falls under the bisabolane-type compound classification.
