Chemical Structure
Description
The occurrence of 2-Methyl-5-[(E)-2-nitrovinyl]furan is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Methyl-5-[(E)-2-nitrovinyl]furan (CAS 61691-99-4), molecular formula C7H7NO3 and molecular weight 153.14 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-Methyl-5-[(E)-2-nitrovinyl]furan (C7H7NO3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 153.14 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
