Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1019186-58-3 6,6-Dimethyl-3,8-dioxo-2-phenyl-2,3,5,6,7,8-hexahydroisoquinoline-4-carboxylic acid.
CATO supplies 1019186-58-3 6,6-Dimethyl-3,8-dioxo-2-phenyl-2,3,5,6,7,8-hexahydroisoquinoline-4-carboxylic acid (CAS 1019186-58-3), a certified reference material (molecular formula C18H17NO4, MW 311.33 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, 1019186-58-3 6,6-Dimethyl-3,8-dioxo-2-phenyl-2,3,5,6,7,8-hexahydroisoquinoline-4-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 311.33 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
