Chemical Structure

Endothal CAS 145-73-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 186.16 g/mol gives Endothal distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Endothal (CAS 145-73-3) is a high-purity analytical reference standard with the molecular formula C8H10O5 and a molecular weight of 186.16 g/mol.

Based on its molecular formula C8H10O5, Endothal contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 186.16 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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 Endothal 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.
