Amoxicillin Trimer Impurity is chemically (4S,4'S)-2,2'-((1R,7R,13R)-1-amino-14-(((2S,5R,6R)-2-carboxy-3,3-dimethyl-7-oxo-4-thia-1-azabicyclo[3.2.0]heptan-6-yl)amino)-1,7,13-tris(4-hydroxyphenyl)-2,5,8,11,14-pentaoxo-3,6,9,12-tetraazatetradecane-4,10-diyl)bis(5,5-dimethylthiazolidine-4-carboxylic acid). It is also known as Amoxicillin Close Ring Trimer. Amoxicillin Trimer Impurity is supplied with detailed characterization data compliant with regulatory guideline. Amoxicillin Trimer Impurity can be used for the analytical method development, method validation (AMV), Quality Controlled (QC) application for Abbreviated New Drug Application (ANDA) or during commercial production of Amoxicillin.

The product can be used as reference standards and further traceability against pharmacopeial standards (USP or EP) can be provided based on feasibility. SynZeal products are for analytical purpose only and not for human use.
