Chemical Structure
Description
Anthraquinone-2-sulfonate sodium salt monohydrate (CAS 153277-35-1), molecular formula C14H19O5SNaH2O and molecular weight 340.37 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Anthraquinone-2-sulfonate sodium salt monohydrate (C14H19O5SNaH2O) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.5, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 340.37 g/mol, it falls into the moderately-high-molecular-weight range. 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.
As a certified reference material (CRM), Anthraquinone-2-sulfonate sodium salt monohydrate 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.
