Chemical Structure

Indeno[1,2-b]indole CAS 248-59-9 chemical structure

Description

Indeno[1,2-b]indole (CAS 248-59-9), molecular formula C15H9N and molecular weight 203.24 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Indeno[1,2-b]indole (C15H9N) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. 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 203.24 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

As a certified reference material (CRM), Indeno[1,2-b]indole meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
