Sodium (6R,7R)-7-((R)-2-(4-carboxy-1H-imidazole-5-carboxamido)-2-phenylacetamido)-8-oxo-3-((4-(2-sulfonatoethyl)pyridin-1-ium-1-yl)methyl)-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylate CAS 85287-61-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Sodium (6R,7R)-7-((R)-2-(4-carboxy-1H-imidazole-5-carboxamido)-2-phenylacetamido)-8-oxo-3-((4-(2-sulfonatoethyl)pyridin-1-ium-1-yl)methyl)-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylate.

Sodium (6R,7R)-7-((R)-2-(4-carboxy-1H-imidazole-5-carboxamido)-2-phenylacetamido)-8-oxo-3-((4-(2-sulfonatoethyl)pyridin-1-ium-1-yl)methyl)-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylate (CAS 85287-61-2), molecular formula C28H25N6O10S2Na and molecular weight 692.65 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Sodium (6R,7R)-7-((R)-2-(4-carboxy-1H-imidazole-5-carboxamido)-2-phenylacetamido)-8-oxo-3-((4-(2-sulfonatoethyl)pyridin-1-ium-1-yl)methyl)-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylate (C28H25N6O10S2Na) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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

As a certified reference material (CRM), Sodium (6R,7R)-7-((R)-2-(4-carboxy-1H-imidazole-5-carboxamido)-2-phenylacetamido)-8-oxo-3-((4-(2-sulfonatoethyl)pyridin-1-ium-1-yl)methyl)-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylate 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.
