Analytical Methodologies in Pharmaceutical Industry

Stacey Smith, Pharma Tech Outlook | Saturday, March 14, 2020

Analytical chemistry is prevalent in the pharmaceutical sector, particularly throughout the drug development process, ensuring the quality, safety, and efficacy of new medications.

FREMONT, CA: There are three broad analytical techniques used in the pharmaceutical sector for assessing structure, isolating analytes, and measuring target molecules. Several types of analytical chemistry procedures, including classical analytical chemistry, chromatography, and spectroscopy. The titrimetric method, which is a rapid qualitative technique for identifying the presence of a certain analyte or medicinal ingredient, is a common classical analytical methodology.

Optimization of function group methods enables the study of kinetic measurements to determine reaction rates. Within the pharmaceutical sector, these approaches have been used to determine the presence of particular pharmaceutical substances such as captopril, gabapentin, and sparfloxacin in commercial dosage forms.

Due to the separation and detection precision of chromatography procedures have a considerable presence in the pharmaceutical business. TLC is a technique for screening unknown compounds in bulk medicines. It is a qualitative technique in that it separates all possible drug ingredients. High-performance TLC is a more advanced variant of the technology that offers the advantage of a shorter run time for complicated mixes and multiple samples or medications.

Additionally, high-performance liquid chromatography (HPLC) separates complex mixtures since it is highly specific, precise, and accurate. Different detectors are used in HPLC, but one that is frequently employed is UV due to its ability to monitor multiple wavelengths simultaneously. HPLC is capable of analyzing a variety of medications during the pharmaceutical formulation process and has long been the industry's dominant technique. When combined with mass spectrometry (LC-MS), it has become the industry's new gold standard for quality control and assurance. Gas chromatography is another type of chromatography separation technology that is frequently employed in the industry. It is used to detect volatile organic substances. It is used to assess contaminants and residual solvents in the pharmaceutical sector.

Spectroscopic approaches are critical in the pharmaceutical business due to their low cost, rapidity, and accuracy. Raman and infrared spectroscopy are frequently used analytical methods. Near-infrared spectroscopy (NIRS) is the most extensively utilized technique in the pharmaceutical business because it is a quick and non-destructive method for analyzing practically any matrix. It is primarily used to test raw materials, ensure quality control, and monitor processes. It has gained widespread recognition in the pharmaceutical business because of the ease with which it can be used to identify physicochemical qualities using a single spectrum.

Thus, analytical chemistry's primary purpose in the pharmaceutical business is to detect and characterize pharmaceutical substances efficiently and effectively to maintain high-quality assurance and quality control.
