Antibiotics

Selman Waksman defined the term antibiotic in 1942 to describe any substance produced by a microorganism that is antagonistic to the growth of other microorganisms in high dilution. While this definition was coined it meant in the same way that substances that kill bacteria, but are not produced by microorganisms were excluded. Not included were synthetic antibacterial compounds such as the sulfonamides, too.

Thanks to proceedings in medicinal chemistry, most of today's antibacterials chemically are semisynthetic modifications of various natural compounds.These include, for example, the beta-lactam antibacterials, which include the penicillins (produced by fungi in the genus Penicillium), the cephalosporins, and the carbapenems

In general many antibacterial compounds are relatively small molecules with a molecular weight of less than 2000 atomic mass units.

  • Miligrams - Tons

    Due to our long experience in this business we are aware of the fact that a few grams or even milligrams are sufficient for research. If you are interested in substances, do not hesitate to contact us regardless how small the required quantity may be. In case the research project is successfully completed and our customer needs larger quantities, we inform the supplier way ahead to enable him to complete the scale-up before you might need larger quantities ranging from kilos to maybe even tons later on. Our supplier is able to make upscale investments in time because he is currently being updated on the development of the market by Cfm Oskar Tropitzsch e.K.

  • Product Search

    Our wide range of products covers a large number of requirements our customers have. We are, however, always prepared to look for substances our customers might need. Due to our global network comprising more than 60 countries we are in a position to offer chemical specialities on short notice. In case we are not able to deliver immediately we keep our customer updated on the situation. At times we have found substances after more than 6 months and were able to supply our customer. This service is free of charge - even if no order will be placed later on.

  • Marketing of Products

    Product knowledge meets business know-how!

    As a trading company doing business throughout the world we attend various symposia, professional conventions or trade fairs at least once a month and offer universities, institutes and research establishments the opportunity to market their products, patents and ideas globally. Moreover we will be happy to find potential partners who are interested in licensing agreements for your patent. In order to achieve this we are regularly in touch with almost all global players in the pharmaceutical industry.

  • Documentation

    • Date of birth of the snake
    • List of possible diseases of the snake
    • The medication the snake got in case of diseases
    • Inoculations the snake got
    • How was the snake fed and what was fed?
    • Which detergents were used to clean the cage?
    • How many offspring did the snake have?

    You need a special documentation for a raw material of your project? Cfm Oskar Tropitzsch e.K. is in touch with partners who can supply these documentations. In order to demonstrate the performance in this sector we would like to give you the example of one of our suppliers who is able to document the following data:

  • Custom Synthesis

    Special projects call for special partners. In cooperation with our producers we offer individual custom synthesis. Documentation (DMF) as per the customers´ requirements is of course included. One of our partners has developed more than 250 molecules in the last five years which were synthesised on a very high scientific level.

  • Search for Suppliers

    It is a problem intrinsic to the pharmaceutical industry that sometimes a research project has developed in connection with an approved drug but there is only one supplier for the raw materials. Cfm Oskar Tropitzsch e.K. will be happy to find a reliable and in terms of quality appropriate second supplier, who will also pass the various audits required.
