Chemical Structure

Triphenylmethane CAS 519-73-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 244.33 g/mol gives Triphenylmethane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Triphenylmethane (CAS 519-73-3) is a high-purity analytical reference standard with the molecular formula C19H16 and a molecular weight of 244.33 g/mol.

Triphenylmethane (C19H16) contains a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

CATO manufactures Triphenylmethane 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.
