11. Location matters — regulatory alignment, logistics, and faster timelines
When choosing a custom synthesis provider, geographic location is more than convenience: it shapes regulatory alignment, shipping times, customs complexity, and the ease of tech transfer. A partner with facilities in the same regulatory jurisdiction can simplify compliance with local guidance (e.g., Health Canada or FDA expectations), facilitate on-site audits, and speed up release testing and documentation. From an operational perspective, shorter shipping distances reduce transit risk for sensitive materials and often lower overall project timelines and costs.
Local presence enables tighter collaboration and faster problem solving.
Having laboratory sites in multiple countries reduces timezone friction and makes in-person meetings, pilot runs, and urgent troubleshooting far easier. For complex PG architectures or rapid iterative optimization, the ability to rapidly move between bench-scale experiments and pilot trials at a nearby facility reduces cycle time and minimizes the risk of miscommunication during technology transfer.
ResolveMass advantage — strategically located labs in Canada and the United States.
ResolveMass Laboratories maintains fully equipped facilities in both Canada and the United States to give clients the best of both worlds: North American regulatory familiarity and flexible capacity for small-batch R&D through to pilot-scale work. This binational footprint supports secure IP handling, rapid sample transfers between analytical and synthesis groups, and streamlined cGMP-ready workflows when projects require regulatory-grade documentation. If your program needs cross-border support—such as U.S. market filings with Canadian-based development—our dual-site model provides the operational resilience to execute efficiently.
Practical benefit: choose location to match your risk profile and timeline.
When you review providers, weigh whether local regulatory experience, reduced transit times, and on-site scale-up capability are priorities for your program. If speed, auditability, and secure transfer of confidential material are important, a partner with strategically located labs—like ResolveMass in Canada and the U.S.—can materially lower program risk and accelerate time to milestone.
