Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 353.12 g/mol gives tetrasodium2-methyl-1,4-naphthylenebis(phosphate) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies tetrasodium2-methyl-1,4-naphthylenebis(phosphate) (CAS 131-13-5), a certified reference material (molecular formula C11H8O8P2Na, MW 353.12 g/mol) for analytical method development and quality control.
Structurally, tetrasodium2-methyl-1,4-naphthylenebis(phosphate) (C11H8O8P2Na) contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 353.12 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), tetrasodium2-methyl-1,4-naphthylenebis(phosphate) 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.
