9-(Diphenylmethylene)-1,4-dihydro-1,4-methanonaphthalene CAS 28591-78-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 9-(Diphenylmethylene)-1,4-dihydro-1,4-methanonaphthalene.

CATO supplies 9-(Diphenylmethylene)-1,4-dihydro-1,4-methanonaphthalene (CAS 28591-78-8), a certified reference material (molecular formula C24H18, MW 306.40 g/mol) for analytical method development and quality control.

The molecular framework of 9-(Diphenylmethylene)-1,4-dihydro-1,4-methanonaphthalene (C24H18) is characterized by a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), 9-(Diphenylmethylene)-1,4-dihydro-1,4-methanonaphthalene 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.
