Open-ring Desulfated Aztreonam Ethyl Ester 2 CAS CATO-C4X-152237

Description

The occurrence of Open-ring Desulfated Aztreonam Ethyl Ester 2 is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Open-ring Desulfated Aztreonam Ethyl Ester 2 (CAS CATO-C4X-152237), a certified reference material (molecular formula C15H23N5O6S, MW 401.44 g/mol) for analytical method development and quality control.

Open-ring Desulfated Aztreonam Ethyl Ester 2 (C15H23N5O6S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
