Chemical Structure
Description
24-Nor Ursodeoxycholic Acid (CAS 99697-24-2) is a high-purity analytical reference standard with the molecular formula C6H9F5 and a molecular weight of 176.13 g/mol.
24-Nor Ursodeoxycholic Acid (C6H9F5) contains fluorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
As a certified reference material (CRM), 24-Nor Ursodeoxycholic 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.
