Aztreonam Open-Ring Ethyl Ester CAS CATO-C4X-152227

Description

Compared with other compounds in its class, the molecular weight of 481.50 g/mol gives Aztreonam Open-Ring Ethyl Ester distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Aztreonam Open-Ring Ethyl Ester (CAS CATO-C4X-152227), molecular formula C15H23N5O9S2 and molecular weight 481.50 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Aztreonam Open-Ring Ethyl Ester is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 481.50 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), Aztreonam Open-Ring Ethyl Ester meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
