Chemical Structure
Description
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.
(3-Amino-6,7,8,9-tetrahydro-5H-cyclohepta[b]thieno[3,2-e]pyridin-2-yl)(4-methoxyphenyl)methanone (CAS 445385-16-0) is a high-purity analytical reference standard with the molecular formula C20H20N2O2S and a molecular weight of 352.45 g/mol.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, (3-Amino-6,7,8,9-tetrahydro-5H-cyclohepta[b]thieno[3,2-e]pyridin-2-yl)(4-methoxyphenyl)methanone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 352.45 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).
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.
