Alternative routes for supply-chain resilience

When a key intermediate or reagent is on backorder or has a single supplier with a 12-week lead time, you don't need a better route, you need a different route. This tutorial finds alternatives that bypass the bottleneck.

Steps

1. Identify the constrained molecule. This is usually one specific intermediate or reagent your current route depends on.
2. Open the retrosynthesis form. Submit your target with two different Specify Starting Material values:
   • Submission A: the cheap-and-available alternative starting material you'd prefer to start from.
   • Submission B: leave starting material unspecified, but set precedent to Novel to surface unconventional disconnections that may not require the constrained intermediate at all.
3. Compare the results. Submission A finds routes that begin from your alternative starting material directly. Submission B may surface routes that take a wholly different disconnection path.
4. For each promising alternative, hover over the route nodes to confirm the bottleneck molecule does NOT appear anywhere in the tree.
5. Cross-check vendor availability for every node in the alternative route, especially intermediates the vendor lookup returns more than 5 suppliers for. Multi-vendor sourcing is the resilience signal you actually want.
6. Favorite the route that gives you the cleanest sourcing diversity.

Output

A backup route that uses different building blocks from your current production path. Even if you don't switch immediately, having the alternative documented closes a real supply-chain risk.
