Diethyl 2-(3,5-diiodo-4-(4-methoxyphenoxy)benzyl)malonate CAS 94861-76-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Diethyl 2-(3,5-diiodo-4-(4-methoxyphenoxy)benzyl)malonate.

Diethyl 2-(3,5-diiodo-4-(4-methoxyphenoxy)benzyl)malonate (CAS 94861-76-4), molecular formula C21H22I2O6 and molecular weight 624.20 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a flavonoid core, a hydroxyl group, an ether linkage, iodine substitution, Diethyl 2-(3,5-diiodo-4-(4-methoxyphenoxy)benzyl)malonate is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 624.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), Diethyl 2-(3,5-diiodo-4-(4-methoxyphenoxy)benzyl)malonate 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.
