1,3-Bis(2,3-dihydro-1h-indol-1-yl)propane-1,3-dione CAS 128099-74-1

Description

The occurrence of 1,3-Bis(2,3-dihydro-1h-indol-1-yl)propane-1,3-dione is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1,3-Bis(2,3-dihydro-1h-indol-1-yl)propane-1,3-dione (CAS 128099-74-1), molecular formula C19H18N2O2 and molecular weight 306.36 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 1,3-Bis(2,3-dihydro-1h-indol-1-yl)propane-1,3-dione (C19H18N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 306.36 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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 1,3-Bis(2,3-dihydro-1h-indol-1-yl)propane-1,3-dione 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.
