(Chemical Registration and Publishing System)

Multiuser chemical information system based on open access software. Read more




















The standard import functionality and the standard data dictionary might not be what you want. We offer services to adjust the system to your needs. We have a lot of experience cleaning your data before we register them into the system: 

Structure checker: This application checks the correct valence, weeds out wrong structures

Standardizes structures, for instance converts 5 valence nitrogen in 3 valence nitrogen (e.g. uncharged nitro groups gets converted in charged nitro groups)

Name checker: This application is able to correct errors in names, i.e. if words are spelled wrong like immidazole instead of imidazole. Such a correction cannot be 100%, but it finds many errors.  

CAS number checker: This application checks if the CAS Registry Number is a valid CAS number. It finds incorrect assigned CAS numbers. Often the CAS number given is in reality for a salt and not for the parent. We only have access to CAS numbers that are in the public domain, but this are already quite a lot.

Data enrichment: This application can add

  • Synonyms

  • CAS Registry Numbers

  • IUAPAC names

  • PASS parameters (predicted biological activities)

  • …and more

to a compound record.


For certain customers we have applications that provide data directly:

Names of potential suppliers for a certain compound. You would like to give some identifier like synonym, CAS Number, AKos Number, IUPAC name, etc. and get quickly a list of suppliers.

Get quickly the prices for compounds from other suppliers.

Biochemfusion has a long experience on building systems for peptides. The system can be extended to handle peptides sequences with structure modifications.

Search for structure-modified peptides 

Proteax® - easy interchange of full structures and three or one letter codes for peptides

Biochemfusion's Proteax software suite makes it easy to handle modified proteins and protein derivatives. Use Proteax with Microsoft® Excel® or Oracle® databases to register and analyze your protein structures.

The chemically-aware Proteax engine enables you to work with post-translationally and chemically modified protein sequences. Protein data can therefore be transferred directly to bioinformatics tools, chemistry tools and to and from mass spectrometry instruments.

Proteax is included in iScienceSearch and is the first application that makes is possible to search  and analyze the results for structure-modified proteins.


Benefit from the know-how of specialists 

Consulting for biological registration systems

Dr. Jan Holst the producer of Proteax and owner of BioChemFusion can help you building a biological registration system. He and other from ( have the experience and know-how to build systems.

Low cost offer of a screening compounds 
















Special Offer:

Several of our suppliers offer larger collections for a very attractive price. We supply 5 mg of dry powders in vials or well-plates. Shipping cost is 150 € to Europe and 200 € to USA, of course, in the case of big order we'll send free of charge. Below is only one example of such a special offer.
The files contain ca. 12000 structures. We also extracted the scaffolds using the KNIME Murcko node. We have added the PASS parameters to the download files. This enables you, not only to select your molecules by structure, but also by estimated biological effects (toxicities, gene expressions, etc.)

Save money by avoiding unnecessary expensive testing in green-house and field. 


Database of unpublished experimental results of 50’000 agro chemicals

AKos GmbH is reselling a databases of ca.  50’000 compounds and ca. 1’000’000 test results. The compounds are potential herbicides and fungicides. The rights to these data were rightfully acquired when the LEUNA group of companies were dissolved and sold. Many of these data have importance for REACH, and research. The data were very unstructured and were recently reworked into XML files, ACCESS database and the structures are in SDFiles. 

1 Million

What happens when I want to change the vendor?

What happens when I need to use my own server, due to security reasons? 



Academic package:
electronic lab journal (ELN)

Many professors would like to use an ELN. However, they work with companies and they use paper notebooks due to security reasons. They are not allowed to put anything in the cloud.

The other issue is what happens to the data, if they want to change the vendor?

AKos GmbH and Scilligence agreed to offer a solution where you can use the Scilligence software on your own server. You still can use the cloud, if you prefer. If you decide to terminate the agreement, you will get a SQL database package with your data.

Onsite ELN Academic Package up to 20 users: License fee 250/user – 5,000 Euro annual (includes maintenance), 10000 Euro perpetual (20% Annual Maintenance fee)
Installation and training  2000 Euro + expenses

Please send us an email to to schedule a demo, begin an evaluation, or request further information.


Euro per year plus 2000 Euro installation
