Chemical Structure
Description
Spiro[cyclohexane-1,3'-indoline] (CAS 4740-63-0) is a high-purity analytical reference standard with the molecular formula C13H17N and a molecular weight of 187.28 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, Spiro[cyclohexane-1,3'-indoline] is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 187.28 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
