Diphenyl (4-(1,3-dioxoisoindolin-2-yl)butyl)phosphonate CAS 866153-22-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Diphenyl (4-(1,3-dioxoisoindolin-2-yl)butyl)phosphonate.

Diphenyl (4-(1,3-dioxoisoindolin-2-yl)butyl)phosphonate (CAS 866153-22-2), molecular formula C24H22NO5P and molecular weight 435.41 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a flavonoid core, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage, Diphenyl (4-(1,3-dioxoisoindolin-2-yl)butyl)phosphonate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 435.41 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), Diphenyl (4-(1,3-dioxoisoindolin-2-yl)butyl)phosphonate 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.
