Chemical Structure

Indophenol Blue CAS 136023-77-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 276.33 g/mol gives Indophenol Blue distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Indophenol Blue (CAS 136023-77-3), molecular formula C18H16N2O and molecular weight 276.33 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Indophenol Blue (C18H16N2O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO manufactures Indophenol Blue 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.
