Sulfo-cyanine3 carboxylic acid, 95% CAS 146368-13-0

Description

The occurrence of Sulfo-cyanine3 carboxylic acid, 95% is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Sulfo-cyanine3 carboxylic acid, 95% (CAS 146368-13-0) is a high-purity analytical reference standard with the molecular formula C31H38N2O8S2 and a molecular weight of 630.77 g/mol.

Sulfo-cyanine3 carboxylic acid, 95% (C31H38N2O8S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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 Sulfo-cyanine3 carboxylic acid, 95% 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.
