(3S,3'S,4'R,6'R,8'S,8'aR)-6-Chloro-8'-(3-chloro-2-fluorophenyl)-6'-(2,2-dimethylpropyl)-3',4',8',8'a-tetrahydro-3',4'-diphenylspiro[3H-indole-3,7'(6'H)-[1H]pyrrolo[2,1-c][1,4]oxazine]-1',2(1H)-dione CAS 897365-81-0 chemical structure

Description

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, (3S,3'S,4'R,6'R,8'S,8'aR)-6-Chloro-8'-(3-chloro-2-fluorophenyl)-6'-(2,2-dimethylpropyl)-3',4',8',8'a-tetrahydro-3',4'-diphenylspiro[3H-indole-3,7'(6'H)-[1H]pyrrolo[2,1-c][1,4]oxazine]-1',2(1H)-dione is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 643.57 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

(3S,3'S,4'R,6'R,8'S,8'aR)-6-Chloro-8'-(3-chloro-2-fluorophenyl)-6'-(2,2-dimethylpropyl)-3',4',8',8'a-tetrahydro-3',4'-diphenylspiro[3H-indole-3,7'(6'H)-[1H]pyrrolo[2,1-c][1,4]oxazine]-1',2(1H)-dione (CAS 897365-81-0), molecular formula C37H33Cl2FN2O3 and molecular weight 643.57 g/mol, is a CATO reference standard with documented purity and traceability.

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.

As a certified reference material (CRM), (3S,3'S,4'R,6'R,8'S,8'aR)-6-Chloro-8'-(3-chloro-2-fluorophenyl)-6'-(2,2-dimethylpropyl)-3',4',8',8'a-tetrahydro-3',4'-diphenylspiro[3H-indole-3,7'(6'H)-[1H]pyrrolo[2,1-c][1,4]oxazine]-1',2(1H)-dione meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
