Custom Synthesis & OEM Services

A molecule that is not in the catalog, your brand on the label, or production-scale volume — none of these are standard catalog orders, and each is scoped project by project.

What we can do

Custom synthesis & chemical modification

Custom reactive groups, linker chemistry and structural modifications specified by the project, including dye derivatives not listed in the catalog.

Custom packaging formats

Packaged to your working quantity, without being limited to the standard pack sizes listed on the product pages.

OEM & private-label packaging

Delivered under your own brand and packaging, with labels, inserts and pack formats to the agreed specification.

Bulk contract supply

Production-scale supply for kit, diagnostic and antibody-conjugation manufacturers, on supply-agreement terms negotiated per project.

What to prepare before the discussion

The more of this you can provide, the more specific the first round of feedback will be. Leave anything you cannot yet fix and add it later.

  • Target product: catalog number (if modifying an existing product), structure or CAS number, required reactive group and linker
  • Specifications: purity requirement, spectral properties, solubility and any other critical release criteria
  • Quantity & packaging: per-batch quantity, pack format, estimated annual volume
  • Application & timing: downstream use (research / kit raw material / diagnostics) and target date for the first delivery
  • Type of engagement: modification of a catalog item, fully custom synthesis, OEM private label or bulk supply

For projects involving unpublished structures or proprietary information, a non-disclosure agreement can be signed before the technical discussion begins.

How it works

  1. 1

    Submit your requirements

    Describe the target product, quantity and type of engagement through the form on this page or by email.

  2. 2

    Technical assessment

    Our technical team assesses the feasibility of the synthetic route, the specifications that can realistically be met and the main risk points, coming back to you on details where needed.

  3. 3

    Proposal & quotation

    You receive a confirmed technical proposal, lead time and quotation. Both lead time and price vary with project scale and difficulty; there is no single published standard.

  4. 4

    Pilot batch & release

    Release testing is completed against the agreed test panel and a Certificate of Analysis (CoA) is issued; production and delivery follow your confirmation.

Custom-synthesized products are handled as a separate order category from catalog items: for non-quality reasons they are not eligible for return once produced.
