Description
CATO manufactures 4-Amino-2-methylbenzofuran-5-ol 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.
4-Amino-2-methylbenzofuran-5-ol (CAS 65874-36-4) is a high-purity analytical reference standard with the molecular formula C9H9NO2 and a molecular weight of 163.17 g/mol.
4-Amino-2-methylbenzofuran-5-ol (C9H9NO2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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.
