Ethyl 2,4-dioxocyclopentanecarboxylate CAS 201611-48-5 chemical structure

Description

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 supplies Ethyl 2,4-dioxocyclopentanecarboxylate (CAS 201611-48-5), a certified reference material (molecular formula C8H10O4, MW 170.16 g/mol) for analytical method development and quality control.

Ethyl 2,4-dioxocyclopentanecarboxylate (C8H10O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO manufactures Ethyl 2,4-dioxocyclopentanecarboxylate 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.
