Chemical Structure

Ethyl 4-Cyclopropyl-2,4-dioxobutanoate CAS 21080-80-8 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 Ethyl 4-Cyclopropyl-2,4-dioxobutanoate.

Ethyl 4-Cyclopropyl-2,4-dioxobutanoate (CAS 21080-80-8) is a high-purity analytical reference standard with the molecular formula C9H12O4 and a molecular weight of 184.19 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, Ethyl 4-Cyclopropyl-2,4-dioxobutanoate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 184.19 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.

CATO manufactures Ethyl 4-Cyclopropyl-2,4-dioxobutanoate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
