Understanding the Challenge of Custom Synthesis Small Molecule Projects
Every Custom Synthesis Small Molecule Case Study begins with challenges like achieving stability, reproducibility, and synthetic feasibility. In this project, the client’s target compound was difficult to handle due to limited data, unstable intermediates, and strict chiral purity needs (>99.5% ee).
To address these hurdles, ResolveMass conducted:
- Comprehensive retrosynthetic pathway analysis
- Stability assessments of intermediates
- Analytical method development using HPLC, NMR, and LC-MS
These steps were supported by computational chemistry simulations that predicted degradation and reaction challenges early. This groundwork reduced rework, improved yields, and ensured each intermediate was characterized precisely.

Phase 1: Designing the Synthetic Route
Route design is the foundation of any custom synthesis small molecule project. It defines the most efficient and sustainable path to build the target compound.
ResolveMass chemists used AI-driven retrosynthetic tools to generate multiple pathways, ranking each by yield, reagent cost, safety, and environmental impact. The chosen route balanced scalability with environmental responsibility.
| Route | Yield (%) | Cost Index | Environmental Impact | Scalability |
|---|---|---|---|---|
| Route A | 72 | 1.2 | Low | High |
| Route B | 85 | 1.0 | Medium | Moderate |
| Route C (Selected) | 88 | 0.9 | Low | High |
This data-based approach ensured efficiency and sustainability. By blending AI with expert insight, the team improved decision-making and shortened the development timeline.

Phase 2: Process Optimization and Analytical Validation
Once the synthetic route was established, process engineers refined each reaction step to increase yield and consistency. Continuous data tracking allowed real-time corrections and reliable performance.
ResolveMass carried out:
- Kinetic monitoring through in-situ FTIR
- Catalyst screening to improve reaction selectivity
- Impurity mapping followed by purification via flash chromatography
Rigorous quality control was maintained with HPLC, GC-MS, and NMR analysis. Statistical modeling helped predict potential deviations, enabling proactive adjustments to maintain quality.
