Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (5S,6R,7E,9E,11E,14Z)-6-(((R)-2-((S)-4-Carboxy-4-(methylamino)butanamido)-3-((carboxymethyl)amino)-3-oxopropyl)thio)-5-hydroxyicosa-7,9,11,14-tetraenoic acid.

(5S,6R,7E,9E,11E,14Z)-6-(((R)-2-((S)-4-Carboxy-4-(methylamino)butanamido)-3-((carboxymethyl)amino)-3-oxopropyl)thio)-5-hydroxyicosa-7,9,11,14-tetraenoic acid (CAS 131391-65-6) is a high-purity analytical reference standard with the molecular formula C31H49N3O9S and a molecular weight of 639.80 g/mol.

The molecular framework of (5S,6R,7E,9E,11E,14Z)-6-(((R)-2-((S)-4-Carboxy-4-(methylamino)butanamido)-3-((carboxymethyl)amino)-3-oxopropyl)thio)-5-hydroxyicosa-7,9,11,14-tetraenoic acid (C31H49N3O9S) 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), (5S,6R,7E,9E,11E,14Z)-6-(((R)-2-((S)-4-Carboxy-4-(methylamino)butanamido)-3-((carboxymethyl)amino)-3-oxopropyl)thio)-5-hydroxyicosa-7,9,11,14-tetraenoic acid 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.
