6’-α-Sialyl-N-acetyllactosamine sodium salt CAS 174757-71-2

Description

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.

6’-α-Sialyl-N-acetyllactosamine sodium salt (CAS 174757-71-2), molecular formula C25H42N2O19 and molecular weight 674.60 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 6’-α-Sialyl-N-acetyllactosamine sodium salt (C25H42N2O19) is characterized by a nitrogen-containing heterocyclic scaffold, an amide 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), 6’-α-Sialyl-N-acetyllactosamine sodium salt 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.
