tert-Butyl 4-bromo-2-oxospiro[indoline-3,4'-piperidine]-1'-carboxylate CAS 1707580-82-2 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 tert-Butyl 4-bromo-2-oxospiro[indoline-3,4'-piperidine]-1'-carboxylate.

tert-Butyl 4-bromo-2-oxospiro[indoline-3,4'-piperidine]-1'-carboxylate (CAS 1707580-82-2), molecular formula C17H21BrN2O3 and molecular weight 381.26 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, tert-Butyl 4-bromo-2-oxospiro[indoline-3,4'-piperidine]-1'-carboxylate (C17H21BrN2O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 381.26 g/mol, it falls into the moderately-high-molecular-weight range. 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.

As a certified reference material (CRM), tert-Butyl 4-bromo-2-oxospiro[indoline-3,4'-piperidine]-1'-carboxylate 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.
