(2Z,2'E)-2,2'-(Quinoxaline-2,3(1H,4H)-diylidene)bis(1-phenylethanone) CAS 253133-06-1 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2Z,2'E)-2,2'-(Quinoxaline-2,3(1H,4H)-diylidene)bis(1-phenylethanone).

CATO supplies (2Z,2'E)-2,2'-(Quinoxaline-2,3(1H,4H)-diylidene)bis(1-phenylethanone) (CAS 253133-06-1), a certified reference material (molecular formula C24H18N2O2, MW 366.41 g/mol) for analytical method development and quality control.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, (2Z,2'E)-2,2'-(Quinoxaline-2,3(1H,4H)-diylidene)bis(1-phenylethanone) is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 366.41 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), (2Z,2'E)-2,2'-(Quinoxaline-2,3(1H,4H)-diylidene)bis(1-phenylethanone) 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.
