Chemical Structure

Diphenylpyraline CAS 147-20-6 chemical structure

Description

As a certified reference material (CRM), Diphenylpyraline 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.

Diphenylpyraline (CAS 147-20-6) is a high-purity analytical reference standard with the molecular formula C19H23NO and a molecular weight of 281.39 g/mol.

Diphenylpyraline (C19H23NO) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
