Chemical Structure

Asperosaponin IV CAS 126778-93-6 chemical structure

Description

Asperosaponin IV (CAS 126778-93-6), molecular formula C49H78O19 and molecular weight 971.13 g/mol, is a CATO reference standard with documented purity and traceability.

Asperosaponin IV (C49H78O19) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), Asperosaponin IV 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.
