Description
CATO manufactures 4-Methoxyfuro[2,3-b]pyridine 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 4-Methoxyfuro[2,3-b]pyridine (CAS 193624-92-9), a certified reference material (molecular formula C8H7NO2, MW 149.15 g/mol) for analytical method development and quality control.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 4-Methoxyfuro[2,3-b]pyridine is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 149.15 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.
