Chemical Structure
Description
As a certified reference material (CRM), 3-Methyl-2-nitrofuran meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
3-Methyl-2-nitrofuran (CAS 38829-39-9), molecular formula C5H5NO3 and molecular weight 127.10 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3-Methyl-2-nitrofuran (C5H5NO3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 127.10 g/mol, it falls into the low-molecular-weight range. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
