Chemical Structure
Description
The occurrence of 2-(Benzo[d][1,3]dioxol-5-yl)-1-oxo-N-(pyridin-4-ylmethyl)-3-(thiophen-3-yl)-1,2,3,4-tetrahydroisoquinoline-4-carboxamide is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2-(Benzo[d][1,3]dioxol-5-yl)-1-oxo-N-(pyridin-4-ylmethyl)-3-(thiophen-3-yl)-1,2,3,4-tetrahydroisoquinoline-4-carboxamide (CAS 1023500-67-5), a certified reference material (molecular formula C27H21N3O4S, MW 483.54 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 2-(Benzo[d][1,3]dioxol-5-yl)-1-oxo-N-(pyridin-4-ylmethyl)-3-(thiophen-3-yl)-1,2,3,4-tetrahydroisoquinoline-4-carboxamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 483.54 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
