1. Challenge: Achieving High Purity and Yield Consistency
Purity and yield are critical in every synthesis project, yet achieving the same results across multiple batches can be difficult. Small variations in temperature, reagent quality, or purification steps can cause major changes in output. These inconsistencies must be controlled to ensure reliable product quality.
Solution:
At ResolveMass Laboratories, we use advanced analytical systems and multi-step purification processes to perfect each synthesis route. In-process controls and validation methods keep yield and purity consistent from small laboratory samples to large production batches. Our analytical experts build impurity profiles and acceptance standards that help fine-tune each process for reliable, regulatory-ready outcomes.
Key Strategies:
- Use HPLC, GC-MS, and LC-MS to monitor impurities.
- Apply Design of Experiments (DoE) for process optimization.
- Maintain detailed batch records for full process traceability.
2. Challenge: Scalability of Synthetic Routes
Scaling a chemical process from lab scale to full production is one of the toughest Custom Synthesis Challenges. Reactions that work well in small volumes may not behave the same when scaled up due to changes in heat transfer, mixing, or reagent flow. Identifying these issues early helps avoid costly problems later.
Solution:
Our workflow includes early-stage scalability studies that test temperature control, mixing methods, and solvent systems before full-scale production. ResolveMass scientists use computer modeling and pilot testing to predict scale-related behavior and make adjustments as needed. This careful approach ensures safe and efficient scale-up from research to manufacturing.
| Stage | Challenge | ResolveMass Solution |
|---|---|---|
| Lab-scale | Limited reaction data | Reaction optimization studies |
| Pilot-scale | Heat/mass transfer issues | CFD simulation and microreactor tech |
| Production | Regulatory documentation | GMP validation and reporting |
3. Challenge: Communication and Transparency in CRO Collaboration
Clear communication is essential for successful CRO partnerships. Misunderstandings or poor data sharing can delay progress and cause misaligned expectations. Without transparency, clients may lose confidence in the process.
Solution:
ResolveMass promotes collaboration through real-time project dashboards, weekly updates, and organized milestone tracking. All analytical data and changes are documented and shared promptly. Dedicated project managers ensure clarity and timely decision-making throughout the project.

4. Challenge: Regulatory and Compliance Barriers
Keeping up with evolving regulations is another major Custom Synthesis Challenge. Non-compliance can delay product approvals or cause costly rework.
Solution:
Our Custom API Development division follows ICH Q7 and cGMP standards to ensure all work meets global regulatory expectations. We prepare validation reports, analytical documentation, and stability studies to support smooth submissions and inspections.
Best Practices:
- Record all synthesis steps under GMP for full traceability.
- Validate all analytical and production methods.
- Maintain secure digital records and audit trails.
5. Challenge: IP Protection and Confidentiality
Protecting intellectual property is vital when working with CROs. Clients need assurance that their formulas, data, and methods are safe and never reused.
Solution:
ResolveMass ensures complete confidentiality with NDAs, secure databases, and isolated project environments. We control user access carefully and use both digital and physical safeguards to prevent unauthorized sharing of proprietary data.
6. Challenge: Limited Access to Specialized Reagents or Equipment
Some projects need rare reagents or advanced analytical tools that are difficult to obtain, creating delays in research and production.
Solution:
Through our global supply network, ResolveMass quickly sources rare chemicals and uses specialized equipment for complex transformations, including chiral separations, peptide coupling, and isotopic labeling. We maintain strong vendor relationships to keep projects on schedule.

7. Challenge: Reproducibility Across Batches
Consistent results between batches are necessary for regulatory and commercial success. Variations caused by process drift or human error can lead to failed batches and added costs.
Solution:
We standardize our processes with detailed SOPs, validated methods, and digital lab notebooks. These tools capture data in real time, making troubleshooting fast and effective. Automated analytics further reduce error and ensure consistent product quality.
8. Challenge: Time and Cost Optimization
Unexpected delays, slow supply chains, or repeated optimization cycles can make projects expensive and time-consuming.
Solution:
ResolveMass applies AI-based scheduling tools and real-time monitoring to detect potential delays before they affect timelines. We use predictive models to optimize resources and prioritize high-value tasks, keeping costs under control and improving project efficiency.

9. Challenge: Early-Stage Discovery Bottlenecks
In early research, delays in identifying viable synthesis routes can slow drug discovery. Quick route selection is essential to keep programs on track.
Solution:
We use computational retrosynthesis and AI-driven predictions to design and test practical synthetic routes faster. Combining computer-based modeling with experimental validation allows our scientists to develop efficient and scalable processes early in the project.
