Ampicillin Open Ring Trimer (CAS No. NA), chemically known as (2R,2'R,2''R,4S,4'S,4''S)-2,2',2''-((1R,4R,7R,10R,13S,16R)-16-amino-1-carboxy-3,6,9,12,15-pentaoxo-4,10,16-triphenyl-2,5,8,11,14-pentaazahexadecane-1,7,13-triyl)tris(5,5-dimethylthiazolidine-4-carboxylic acid) Quaternary sodium salt, is a well-characterized pharmaceutical impurity reference standard associated with Ampicillin. It is widely used by pharmaceutical research laboratories, analytical scientists, contract research organizations (CROs), and quality control laboratories to support impurity identification, chromatographic method development, analytical method validation, and stability studies.

This reference standard plays an important role in ensuring accurate impurity profiling during the development and quality assessment of Ampicillin-based pharmaceutical products. It is suitable for use in analytical techniques such as HPLC, LC-MS, UPLC, and other validated chromatographic methods where reliable impurity characterization is required.

Ampicillin Open Ring Trimer has the molecular formula C48H59N9O13S3 : 4(Na) and a molecular weight of 1066.2 : 4(23.0) g/mol. It is also known by the chemical name (2R,2'R,2''R,4S,4'S,4''S)-2,2',2''-((1R,4R,7R,10R,13S,16R)-16-amino-1-carboxy-3,6,9,12,15-pentaoxo-4,10,16-triphenyl-2,5,8,11,14-pentaazahexadecane-1,7,13-triyl)tris(5,5-dimethylthiazolidine-4-carboxylic acid) Quaternary sodium salt and is identified by CAS No. NA.

Researchers and analytical laboratories utilize this impurity reference standard during pharmaceutical development, quality control testing, method transfer, and regulatory compliance activities. Its use helps support the characterization and monitoring of related substances throughout the product lifecycle.
