Eosin Y bis(tetrabutylammonium salt) CAS 123333-95-9

Description

Compared with other compounds in its class, the molecular weight of 888.35 g/mol gives Eosin Y bis(tetrabutylammonium salt) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Eosin Y bis(tetrabutylammonium salt) (CAS 123333-95-9), molecular formula C20H6Br4O5C16H36N and molecular weight 888.35 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, bromine substitution, Eosin Y bis(tetrabutylammonium salt) is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 888.35 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).

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 Eosin Y bis(tetrabutylammonium salt) 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.
