Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 165.15 g/mol gives 1-(Ethenyloxy)-4-nitrobenzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-(Ethenyloxy)-4-nitrobenzene (CAS 940-14-7) is a high-purity analytical reference standard with the molecular formula C8H7NO3 and a molecular weight of 165.15 g/mol.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 1-(Ethenyloxy)-4-nitrobenzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 165.15 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).
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.
