Chemical Structure

4-(1H-indol-2-yl)phenol CAS 40643-14-9 chemical structure

Description

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.

4-(1H-indol-2-yl)phenol (CAS 40643-14-9), molecular formula C14H11NO and molecular weight 209.24 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 4-(1H-indol-2-yl)phenol is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 209.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO manufactures 4-(1H-indol-2-yl)phenol 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.
