2,2'-(Naphthalene-1,5-diylbis(oxy))bis(1-phenylethan-1-one) CAS 319482-15-0

Description

CATO supplies 2,2'-(Naphthalene-1,5-diylbis(oxy))bis(1-phenylethan-1-one) (CAS 319482-15-0), a certified reference material (molecular formula C26H20O4, MW 396.43 g/mol) for analytical method development and quality control.

Owing to a steroid core, a hydroxyl group, an ether linkage, 2,2'-(Naphthalene-1,5-diylbis(oxy))bis(1-phenylethan-1-one) is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 396.43 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 2,2'-(Naphthalene-1,5-diylbis(oxy))bis(1-phenylethan-1-one) 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.
