Chemical Structure

Alcian Blue CAS 12040-44-7 chemical structure

Description

As a certified reference material (CRM), Alcian Blue 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.

Alcian Blue (CAS 12040-44-7) is a high-purity analytical reference standard with the molecular formula C56H68CuN16S4Cl and a molecular weight of 1192.51 g/mol.

Alcian Blue (C56H68CuN16S4Cl) contains a salt form, a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
