220647-56-3 rac S 33138 rel-N-[4-[2-[(3aS,9bR)-8-Cyano-1,3a,4,9b-tetrahydro[1]benzopyrano[3,4-c]pyrrol-2(3H)-yl]ethyl]phenyl]acetamide CAS 220647-56-3 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 220647-56-3 rac S 33138 rel-N-[4-[2-[(3aS,9bR)-8-Cyano-1,3a,4,9b-tetrahydro[1]benzopyrano[3,4-c]pyrrol-2(3H)-yl]ethyl]phenyl]acetamide.

220647-56-3 rac S 33138 rel-N-[4-[2-[(3aS,9bR)-8-Cyano-1,3a,4,9b-tetrahydro[1]benzopyrano[3,4-c]pyrrol-2(3H)-yl]ethyl]phenyl]acetamide (CAS 220647-56-3) is a high-purity analytical reference standard with the molecular formula C22H23N3O2 and a molecular weight of 361.44 g/mol.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 220647-56-3 rac S 33138 rel-N-[4-[2-[(3aS,9bR)-8-Cyano-1,3a,4,9b-tetrahydro[1]benzopyrano[3,4-c]pyrrol-2(3H)-yl]ethyl]phenyl]acetamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 361.44 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).

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.
