Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 4-(3,4-dichlorophenyl)-2,4-dioxobutanoate.
CATO supplies Ethyl 4-(3,4-dichlorophenyl)-2,4-dioxobutanoate (CAS 93618-67-8), a certified reference material (molecular formula C12H10Cl2O4, MW 289.11 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, Ethyl 4-(3,4-dichlorophenyl)-2,4-dioxobutanoate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 289.11 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), Ethyl 4-(3,4-dichlorophenyl)-2,4-dioxobutanoate 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.
