Chemical Structure
Description
As a certified reference material (CRM), Pyrene-1-sulfonic acid sodium salt 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.
CATO supplies Pyrene-1-sulfonic acid sodium salt (CAS 59323-54-5), a certified reference material (molecular formula C16H9O3SNa, MW 304.29 g/mol) for analytical method development and quality control.
Structurally, Pyrene-1-sulfonic acid sodium salt (C16H9O3SNa) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 12.5, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 304.29 g/mol, it falls into the moderately-high-molecular-weight range. 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.
