Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(2-Nitrovinyl)phenol.
CATO supplies 3-(2-Nitrovinyl)phenol (CAS 3156-44-3), a certified reference material (molecular formula C8H7NO3, MW 165.15 g/mol) for analytical method development and quality control.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 3-(2-Nitrovinyl)phenol 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.
