Chemical Structure
Description
The occurrence of (S)-Ethyl indoline-3-carboxylate is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(S)-Ethyl indoline-3-carboxylate (CAS 83234-86-0), molecular formula C11H13NO2 and molecular weight 191.23 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (S)-Ethyl indoline-3-carboxylate (C11H13NO2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 191.23 g/mol, it falls into the medium-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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
