Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 459.46 g/mol gives Levomefolic Acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Levomefolic Acid (CAS 31690-09-2), a certified reference material (molecular formula C20H25N7O6, MW 459.46 g/mol) for analytical method development and quality control.
The molecular framework of Levomefolic Acid (C20H25N7O6) is characterized by a flavonoid core, 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).
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), Levomefolic 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.
