Aztreonam Impurity 4 CAS 80999-51-5

Description

Compared with other compounds in its class, the molecular weight of 118.13 g/mol gives Aztreonam Impurity 4 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Aztreonam Impurity 4 (CAS 80999-51-5) is a high-purity analytical reference standard with the molecular formula C4H10N2O2 and a molecular weight of 118.13 g/mol.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, Aztreonam Impurity 4 is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 118.13 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.

CATO manufactures Aztreonam Impurity 4 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
