Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,2'-(Naphthalene-1,5-diylbis(oxy))bis(1-(4-chlorophenyl)ethan-1-one).
CATO supplies 2,2'-(Naphthalene-1,5-diylbis(oxy))bis(1-(4-chlorophenyl)ethan-1-one) (CAS 383148-10-5), a certified reference material (molecular formula C26H18Cl2O4, MW 465.32 g/mol) for analytical method development and quality control.
Based on its molecular formula C26H18Cl2O4, 2,2'-(Naphthalene-1,5-diylbis(oxy))bis(1-(4-chlorophenyl)ethan-1-one) contains a steroid core, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 465.32 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
