Chemical Structure

Cyanine CAS 523-42-2 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 538.51 g/mol gives Cyanine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Cyanine (CAS 523-42-2), molecular formula C29H35N2I and molecular weight 538.51 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C29H35N2I, Cyanine contains a nitrogen-containing heterocyclic scaffold, a nitrile group, iodine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 538.51 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

As a certified reference material (CRM), Cyanine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
