Description

Compared with other compounds in its class, the molecular weight of 506.01 g/mol gives Indoine blue distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Indoine blue (CAS 4569-88-4) is a high-purity analytical reference standard with the molecular formula C30H24N5OCl and a molecular weight of 506.01 g/mol.

Structurally, Indoine blue (C30H24N5OCl) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 21.0, corresponding to approximately 21 ring(s) or double-bond equivalent(s). With a molecular weight of 506.01 g/mol, it falls into the moderately-high-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), Indoine blue 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.
