Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Cyano-6-methoxy-4-phenylisoquinoline-1-carboxylic acid.
3-Cyano-6-methoxy-4-phenylisoquinoline-1-carboxylic acid (CAS 849547-30-4) is a high-purity analytical reference standard with the molecular formula C18H12N2O3 and a molecular weight of 304.30 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 3-Cyano-6-methoxy-4-phenylisoquinoline-1-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 304.30 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.
