(E)-2-(9,10-dioxo-9,10-dihydroanthracen-2-yl)acetaldehyde O-methyl oxime CAS 338961-91-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (E)-2-(9,10-dioxo-9,10-dihydroanthracen-2-yl)acetaldehyde O-methyl oxime.

CATO supplies (E)-2-(9,10-dioxo-9,10-dihydroanthracen-2-yl)acetaldehyde O-methyl oxime (CAS 338961-91-4), a certified reference material (molecular formula C17H13NO3, MW 279.29 g/mol) for analytical method development and quality control.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, (E)-2-(9,10-dioxo-9,10-dihydroanthracen-2-yl)acetaldehyde O-methyl oxime is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 279.29 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), (E)-2-(9,10-dioxo-9,10-dihydroanthracen-2-yl)acetaldehyde O-methyl oxime 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.
