Overview of Pharmaceutical Analysis

Pharmaceutical analysis is the science of obtaining, analyzing, and quantifying drug substances.
It is crucial for quality control, drug development, stability testing, and regulatory compliance.

Key Objectives

Identity: Confirming the identity of drug substances.
Purity: Assessing the absence of impurities and contaminants.
Potency: Measuring the concentration and effectiveness of active ingredients.
Stability: Evaluating how drug formulations change over time under various conditions.

Types of Pharmaceutical Analysis

Qualitative Analysis
- Determines the chemical composition or identity of a substance.
- Techniques: Thin Layer Chromatography (TLC), Infrared (IR) Spectroscopy.
Quantitative Analysis
- Measures the amount or concentration of a compound in a sample.
- Techniques: High-Performance Liquid Chromatography (HPLC), Mass Spectrometry (MS).
Physical Analysis
- Examines the physical properties of drug substances (e.g., appearance, melting point).
- Techniques: Microscopy, Thermogravimetric Analysis (TGA).

Common Techniques in Pharmaceutical Analysis

Chromatography: Separation of components; includes TLC, HPLC, and Gas Chromatography (GC).
Spectroscopy: Identification and quantification using light interaction; includes UV-Vis, NMR, and MS.
