Capabilities | Contract & Toll Manufacturing

Your chemistry, made at scale in the U.S.

From lab validation to full commercial production, our Dayton, Tennessee team runs your process with the same care we bring to our own products. You keep your IP and your focus. We handle the execution.

Operations with a fully in-house team

Toll or contract.
You choose how much we take on.

Not sure which fits? We'll help you decide.

Toll manufacturing

You supply the raw materials and process; we provide the plant, people and equipment to make it for you. Best for: established products and customers who manage their own supply.

Contract manufacturing

We source the raw materials and run the full process from start to finish. Best for: teams that want one partner to take the whole job off their plate.

A partner that runs chemistry every day.

Validated once, run at scale.

Validation and commercial batches run on the same reactors, so there is no re-qualification when you scale.

No subcontractors

Process engineering, quality, regulatory, EHS and analytical teams are all on site.

Your IP, protected

Every project starts under NDA and follows a structured technology transfer process.

Capacity without capital

Add production without building or expanding a plant.

Demonstrated chemistries

  • Acetal formation
  • Esterification
  • Aldol condensation
  • Claisen rearrangement
  • Cycloadditions

No surprises.

01

Quotation & NDA

We review your chemistry, volumes and timeline, scope the project and put IP protection in place before any technical exchange.
02

Pre-production

Process specification transfer, raw material sourcing, lab qualification and a signed quality agreement.
03

Production & release

Campaign execution with in-process testing, full documentation and a CoA with every shipment.
04

Quality & regulatory support

Ongoing QA, regulatory documentation, supplier qualification materials and audit readiness.

Backed by an integrated U.S. platform.

Quality agreement ready, a CoA with every shipment, and documentation to support your audit.

Frequently asked questions

What is the difference between toll and contract manufacturing?
In toll manufacturing, you supply the raw materials and process, and we provide the plant, team and equipment. In contract manufacturing, we also source the raw materials and manage the full process.
How do you protect my formulation?
Every project follows a structured, IP-protected Technology Transfer Process and starts under NDA. You retain ownership of your formulation.
What scale can you run?
From benchtop development in lab reactors (500 milliliters to 20 liters) to commercial batches in production reactors up to 3,000 gallons (about 11,400 liters).
Do I have to re-qualify when I move to full production?
No. Validation and commercial production run on the same reactors, at the same site, with the same team.
