Chemical Structure
Description
(1,4-Diphenyl-1H-pyrrol-3-yl)methanol (CAS 1355334-89-2), molecular formula C17H15NO and molecular weight 249.31 g/mol, is a CATO reference standard with documented purity and traceability.
(1,4-Diphenyl-1H-pyrrol-3-yl)methanol (C17H15NO) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), (1,4-Diphenyl-1H-pyrrol-3-yl)methanol 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.
