5'-Aminospiro[cyclohexane-1,3'-indolin]-2'-one CAS 156232-57-4

Description

The occurrence of 5'-Aminospiro[cyclohexane-1,3'-indolin]-2'-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5'-Aminospiro[cyclohexane-1,3'-indolin]-2'-one (CAS 156232-57-4), molecular formula C13H16N2O and molecular weight 216.28 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 5'-Aminospiro[cyclohexane-1,3'-indolin]-2'-one is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 216.28 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.

As a certified reference material (CRM), 5'-Aminospiro[cyclohexane-1,3'-indolin]-2'-one 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.
