Chemical Structure

Euphorbia Factor L2 CAS 218916-51-9 chemical structure

Description

Euphorbia Factor L2 (CAS 218916-51-9), molecular formula C38H42O9 and molecular weight 642.73 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, Euphorbia Factor L2 is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 642.73 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), Euphorbia Factor L2 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.
