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 2-(benzofuran-2-carbonyl)hydrazinecarboxylate.
CATO supplies Ethyl 2-(benzofuran-2-carbonyl)hydrazinecarboxylate (CAS 78620-34-5), a certified reference material (molecular formula C12H12N2O4, MW 248.23 g/mol) for analytical method development and quality control.
Ethyl 2-(benzofuran-2-carbonyl)hydrazinecarboxylate (C12H12N2O4) 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.
CATO manufactures Ethyl 2-(benzofuran-2-carbonyl)hydrazinecarboxylate 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.
