Description
CATO manufactures Ethyl 2,3-dioxoindoline-6-carboxylate 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.
CATO supplies Ethyl 2,3-dioxoindoline-6-carboxylate (CAS 1263282-64-9), a certified reference material (molecular formula C11H9NO4, MW 219.19 g/mol) for analytical method development and quality control.
Ethyl 2,3-dioxoindoline-6-carboxylate (C11H9NO4) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
