GLP Identity Tests and Nano Test Solutions for Pharmaceutical Products
In the pharmaceutical industry, patient safety and product quality are undoubtedly the two most important factors. A medicinal product must be checked before market launch and at every stage of the manufacturing process. This is exactly where the GLP identity checks for Pharmaceutical Products (Identity Tests) come into play. Good Laboratory Practice (GLP) is a quality system that ensures that these tests are performed reliably, repeatable and in accordance with international standards.
The "identity" of a pharmaceutical product refers to its molecular structure, chemical formula and physical properties. Using a false raw material or cross-contamination in the production line can lead to irreparable consequences. Therefore, the identity checks carried out as part of the GLP serve to analytically prove that the product is actually the "desired active ingredient".
The importance of identity checks in pharmaceutical products
Identity checks are not only an analysis, but also a legal obligation. Regulators such as the FDA, EMA and TİTCK require proof that these tests have been carried out in accordance with the GLP principles in the case of approval requests and, through routine quality controls. Without identity verification, the release (release) of a product is not possible.
GLP standards set strict regulations in areas such as personnel training, device calibration, standard work instructions (SOP) and data integrity. As a result, the results achieved are internationally recognized. These tests also play an important role in combating counterfeit medicines and ensuring security in the supply chain.
Basic analytical methods within the framework of the GLP
Several analytical techniques can be combined to identify a pharmaceutical product or a pharmaceutical agent (API). The choice of method depends on the structure of the molecule and the respective pharmacopoeia monograph (e.g. USP, European pharmacopoeia).
1. Spectroscopic Procedures
- Fourier Transform Infrared Spectroscopy (FTIR): is considered the "fingerprint" of the molecule. By analyzing the vibrational bands of the functional groups, it is demonstrated that the substance is identical to the standard reference material.
- UV-VIS spectrophotometry: measures the absorption of molecules containing chromophore groups in particular, at certain wavelengths. Ideal for fast screening.
- Core resonance (NMR): The most powerful technique for elucidating the molecular structure. is used in GLP studies in particular to verify complex molecules.
2. Chromatographic Methods
- High Performance Liquid Chromatography (HPLC): Identification is usually done by comparing the retention times.
- Thin Layer Chromatography (TLC): It is a cost-effective and effective method, in particular for identifying products of plant origin and certain excipients.
3. Thermal Analysis and Miscellaneous
- Differential Scanning Calorimetry (DSC): It is of crucial importance in the analysis of polymorphisms (different crystal structures of the same molecule).
Comparison of the methods used in GLP identity checks
The following table summarizes the basic characteristics of the methods most commonly used in the GLP Identity Tests for Drugs:
| Analytical Method | Measuring principle | Advantages | Typical scope |
|---|---|---|---|
| For | Molecular Vibration Bands | Fast, non-destructive, high specificity | Verification of raw materials and finished products |
| HPLC | Chromatographic Separation + Detector | High sensitivity, can be combined with quantity determination | Purity and identity determination of active ingredients |
| Dsc | Heat flow difference (melting/crystallization) | Detection of polymorphic and amorphous structures | Solid dosage forms, physical stability |
| NMR | Magnetic resonance of atomic nuclei | Precise structure determination, versatility | Unknown impurities, registration of new molecules |

Result
The safety of a pharmaceutical product begins with its correct identification. GLP-compliant pharmaceutical identity checks provide scientific evidence that the product is the molecule specified in the formulation. Incorrect identification can lead to recall costs in the millions and endanger the patient's health. At a time when regulations are getting stricter by the day, working with a reliable and fully GLP-compliant partner like Nano-Test is the most sensible way to protect your brand's reputation and public health.
