Introduction: Why Thermal Testing Matters in Drug Development
In the pharmaceutical industry, it’s crucial to understand how a drug breaks down when exposed to heat. Poor thermal stability can cause safety concerns, failed clinical trials, or regulatory rejection. That’s why scientists use thermogravimetric analysis (TGA) to monitor weight changes in a compound as the temperature rises. It helps identify the exact points where degradation begins. This TGA Analysis Pharmaceutical Case Study highlights how such insights are vital for designing stable formulations that perform well under real-world storage conditions.
This TGA Analysis Pharmaceutical Case Study focuses on a real case handled by ResolveMass Laboratories. They tested a new drug molecule and used the data to fix its formulation, making it ready for further clinical trials. The findings not only improved the product’s shelf life but also ensured it could meet regulatory expectations for thermal stability.
When used early in development, TGA results can guide decisions about packaging, storage, and ingredient selection. It gives pharmaceutical scientists a powerful way to prevent failure before a product even reaches patients.
What is TGA and Why It’s Essential in Pharmaceuticals
What Is Thermogravimetric Analysis (TGA)?
TGA is a laboratory method that tracks weight changes in a sample as it is gradually heated. These changes can reveal moisture loss, decomposition stages, and thermal stability. It helps scientists understand how different components in a drug behave at various temperatures. This information is crucial for ensuring the drug remains safe and effective throughout its shelf life. TGA also supports regulatory compliance by providing detailed thermal profiles required during product submission.
Why TGA Is Important in Pharma
- Finds the temperature at which a drug begins to break down
- Measures leftover moisture or solvent in the material
- Helps choose the right storage and packaging solutions
- Supports regulatory filing with real scientific data
When working with new drug compounds, using TGA early helps avoid surprises later.

Background and the Problem
ResolveMass Laboratories received a new chemical entity (NCE) for testing. During early trials, the drug showed a drop in strength when exposed to heat and moisture. The sponsor wanted to understand the reason and fix the issue before moving forward. Since stability is a key factor in drug approval, identifying the degradation source was critical for the compound’s future development. Delays in resolving this could have led to costly reformulations or halted progress.
Goal of the Analysis
The main goal was to study the thermal degradation profile of the molecule. TGA was used to reveal at what temperatures the drug started to lose weight, and why. By pinpointing the exact stages of thermal breakdown, the team aimed to adjust the formulation for better stability. This would help ensure consistent performance across storage, transportation, and clinical use.
TGA Testing Steps Followed by ResolveMass
| Step | Details |
|---|---|
| Sample Size | 5 mg of the drug tested under a dry, inert atmosphere |
| Heating Rate | 10°C per minute up to 600°C |
| Conditions | Compared performance in both nitrogen and air environments |
| Detection Tool | Tracked weight loss and key temperature points |
This careful setup ensured accurate and repeatable results in both dry and oxidative settings.

What the TGA Results Showed
The TGA analysis showed three key weight loss stages:
- Around 80–120°C – Loss of water from the drug, showing it was absorbing moisture from the air.
- Around 220–250°C – Decomposition of important chemical groups in the molecule.
- Around 350°C – Complete breakdown of the molecule structure.
These results pointed to a serious risk of hydrolysis, meaning the drug broke down when exposed to moisture. The team used this data to adjust how the drug was stored and handled.

Using Other Methods Alongside TGA
TGA + DSC + FTIR = Better Insights
To confirm the findings, the team also used:
- DSC (Differential Scanning Calorimetry): Measured heat flow to detect physical changes
- FTIR (Fourier-transform infrared spectroscopy): Identified gases released during heating
Using these together with TGA gave a full picture of what was happening during the degradation process.

How the TGA Analysis Changed the Drug’s Development Path
The insights from this TGA Analysis Pharmaceutical Case Study helped the team take clear steps:
- Switched to anhydrous excipients that don’t absorb water
- Chose desiccant-based packaging to keep the product dry
- Set up low-humidity storage protocols for long-term safety
Thanks to these changes, the drug moved forward to Phase II clinical trials with improved stability and reduced degradation risks.

Top FAQs: TGA Analysis Pharmaceutical Case Study
TGA is essential in pharmaceutical development because it shows how a drug behaves under heat. It reveals weight changes, moisture loss, and decomposition points that are critical for stability. By identifying these thermal behaviors early, developers can create safer, more reliable formulations. This is clearly demonstrated in the TGA Analysis Pharmaceutical Case Study by ResolveMass.
Yes, TGA is very helpful in the early stages of drug research and development. It allows teams to spot instability risks before moving into costly formulation or clinical phases. By using TGA early, companies can make smarter decisions and avoid problems later in the process.
Absolutely. In manufacturing, TGA helps ensure that raw materials and finished products meet stability and quality standards. It’s often used for batch-to-batch consistency checks, raw material validation, and monitoring changes in product behavior during scale-up.
Yes, TGA can indicate the presence of residual solvents when weight loss is observed at lower temperatures. When paired with other tools like FTIR or evolved gas analysis, TGA can even help identify which volatile substances are being released. This supports regulatory compliance for solvent limits.
Signs of degradation in a TGA curve include sharp weight loss at specific temperature ranges and multi-step breakdown patterns. Sudden drops or shifts in the curve show where thermal events, such as decomposition or volatilization, are happening. These markers are vital in understanding a drug’s thermal limits.
