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 3-Methoxyfuro[2,3-c]pyridine-2-carboxylic Acid ethyl ester.
CATO supplies 3-Methoxyfuro[2,3-c]pyridine-2-carboxylic Acid ethyl ester (CAS 521948-13-0), a certified reference material (molecular formula C11H11NO4, MW 221.21 g/mol) for analytical method development and quality control.
3-Methoxyfuro[2,3-c]pyridine-2-carboxylic Acid ethyl ester (C11H11NO4) 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. 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 3-Methoxyfuro[2,3-c]pyridine-2-carboxylic Acid ethyl ester 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.
