Custom Synthesis

Custom synthesis for industrial and academic R&D

Complex, multi-step or enantioselective custom synthesis for industrial or research applications is our core competency. We pride ourselves on a 20 year track record of success in supporting the diverse industries with their chemistry and innovation challenges. Our scientists specialize in organic and organometallic synthesis including polymers, from lab to pilot quantities. Taros provides a customer-centric and flexible contract synthesis model with diverse services:

  • Reverse-engineering and custom synthesis of commercial products or key raw materials
  • Generation of new IP and patent validation services within contract synthesis
  • Reference substances and standards, tracers, PET-ligands etc.
  • Stable isotopically labelled compounds
  • Metabolites and impurities
  • Steroid and Vitamin D Synthesis
  • Carbohydrate synthesis
  • Fine & specialty chemicals (additives like photoinitiators, OLED chemicals, etc.)
  • Custom monomers and polymers (polymeric dispersions)
  • Complex dyestuff (diazo, textile, indicator, holographic, photo & security)
Discovery and Optimization of synthetic routes in organic chemistry research


Biotechs simply concentrate on their research and development tasks while our experienced chemists take care of all related synthetic chemistry challenges.

Medtech and Healthcare

From new release mechanisms in band-aid material to the development of chemistry for innovative dual modes of action to help make use of new imaging techniques (PET).

Display Technologies

Innovative display technologies require performance chemicals that allow tomorrow’s visual applications in handheld devices, car interfaces or further intelligent equipment.


Providing innovative but cost efficient early drug discovery services and technologies to our pharma customers is what drives our multidisciplinary scientists at Taros.

Chemical Industry

From literature research to pilot plant – we deliver sophisticated chemicals with full IP to our customers to help them achieve their product development goals.

Coatings and Dyes

Your R&D teams have a specific idea about how the surface should perform by modulating the coating or the curing? Get in touch with our scientists to discuss your chemistry challenge.

Research Institutes and Academia

Great academic research often requires industrial backing and excellent synthesis capacities to bring ideas to the market – for many years we have been closing that gap.

Flavors and Cosmetics

Get in touch with us if you’d like to discuss the development of new or the improvement of existing synthetic molecules for fragrances, oral  and skin care applications or aroma molecules.

Consumer Goods

Smarter consumer goods require both improved properties and chemicals that provide an acceptable ecological footprint during their entire life cycle.
