Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 322.83 g/mol gives Tert-butyl 5-chlorospiro[indoline-3,4'-piperidine]-1-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Tert-butyl 5-chlorospiro[indoline-3,4'-piperidine]-1-carboxylate (CAS 1160247-22-2) is a high-purity analytical reference standard with the molecular formula C17H23ClN2O2 and a molecular weight of 322.83 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, Tert-butyl 5-chlorospiro[indoline-3,4'-piperidine]-1-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 322.83 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.
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.
