Long Term Storage
Drug storage is one of the pharmacist's most crucial responsibilities. As a result, suitable means for ensuring compliance with these responsibilities must be created and executed.

It is a phenomenon in which two or more compounds share the same chemical formula but have different structural formula and properties. This is primarily due to variations in structural or spatial arrangements.
Types of Isomerism:
Structural Isomerism
Stereo Isomerism
Infrared spectroscopy is the study of how infrared light interacts with molecules. This can be assessed in three different ways: absorption, emission, and reflection. This technique is most commonly employed in organic and inorganic chemistry. Chemists use it to identify functional groups in molecules. IR Spectroscopy measures the vibrations of atoms, which The IR transmitter continuously emits IR light, while the IR receiver constantly detects reflected light.
Inert gases are chemically inactive and will not react with many things. Inert gases are utilized for a variety of applications throughout sectors, including welding, chemical processing, and filler gases in light sources. They are: helium, neon, argon, krypton, xenon, and radon.
High performance liquid chromatography, also known as high-pressure liquid chromatography, is a chromatographic technique for separating a mixture of substances that is used in biochemistry and analytical chemistry to identify, measure, and purify the mixture's constituent components. A liquid sample is injected into a solvent stream (mobile phase) that flows through a column containing a separation medium (stationary phase). As samples travel through the column, they separate from one another through a process known as differential migration.
An analytical method that can be used on gas, liquid, and solid samples (components that evaporate due to heat) is gas chromatography (GC). When a GC system is used to investigate a mixture of compounds, each compound can be identified and measured separately.
A functional group is an atom or group of atoms inside a molecule that exhibits comparable chemical properties across several molecules. Even if the rest of the molecule is very different, certain functional groups behave in predictable ways.
Organic molecules vary widely in size, and while studying functional groups, we want to focus on the atoms involved. As a result, the abbreviation R is employed in certain cases.
Flash column chromatography is a type of chemical separation used to purify chemical mixtures. It is also known as flash purification because of its use as a purification procedure. It is also known as medium-pressure chromatography.
In chemistry, extraction is a procedure that involves separating a material from a matrix. Partition theory describes an equilibrium situation that occurs when a solute is distributed between two phases. There are two forms of extraction: liquid-liquid extraction (also known as solvent extraction) and solid-liquid extraction. Both extraction methods rely on the same principle: the separation of chemicals based on their relative solubility in two separate immiscible liquids or solid matter molecules.
The European Pharmacopoeia (Ph.Eur) is a pharmacopeia published by the European Directorate for the Quality of Medicines and Healthcare (EDQM) on behalf of the Council of Europe and all signatory nations to Treaty Number 050. The Ph.Eur supports public health through its monographs and general chapters, which develop and communicate scientifically valid criteria for assessing and controlling the quality of medicines and excipients. It was founded on July 22, 1964, when the Convention on the Development of a European Pharmacopeia became available for signature.
