The occurrence of 3-Methylindoline is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-Methylindoline (CAS 4375-15-9) is a high-purity analytical reference standard with the molecular formula C9H11N and a molecular weight of 133.19 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 3-Methylindoline is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 133.19 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.
CATO manufactures 3-Methylindoline under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
