On synthesis
Antibiotic impurities and related substances are controlled because they can alter potency, safety or the impurity profile of the finished product. Laboratories use them to identify and quantify the species that appear in a related-substances or stability-indicating method, and to demonstrate that the method separates everything the specification limits. The material supplied here is documented lot by lot, so the analytical value used in a calculation can be traced back to a certificate.
Fosfomycin Impurity 54 (CAS 438210-39-0), molecular formula C3H5O4P 2*Na and molecular weight 136.04 2*22.99. It is also recorded as Fosfomycin Diastereomer 1; trans-(3-Methyloxiranyl)phosphonic acid; (1S,2S)-1,2-Epoxypropylphosphonic acid. This item is made to order. Send the impurity designation, the method and the quantity required and we will come back with availability, documentation and lead time.

This is the product specification. Typical purity and assay values are those measured on a released lot and stated on that lot’s certificate of analysis; the certificate for the lot shipped with your order travels with the goods. A specification sheet and a certificate of analysis are different documents and are not interchangeable. A sample certificate can be requested while the batch is being prepared.
