Chemical Structure
Description
As a certified reference material (CRM), Ponfibrate - API Standards 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.
Ponfibrate - API Standards (CAS 53341-49-4), molecular formula C18H16Cl2O4 and molecular weight 367.22 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, a hydroxyl group, an ether linkage, chlorine substitution, Ponfibrate - API Standards is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 367.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
