Chemical Structure
Description
CATO manufactures 2,5-Dimethyl-3-nitrofuran 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.
2,5-Dimethyl-3-nitrofuran (CAS 61759-73-7), molecular formula C6H7NO3 and molecular weight 141.12 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 2,5-Dimethyl-3-nitrofuran is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 141.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
