Description

As a certified reference material (CRM), 58320-73-3 Polyethylene glycol monomethyl ether p-toluenesulfonate, M.W. 5.000 MFCD00025910 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.

58320-73-3 Polyethylene glycol monomethyl ether p-toluenesulfonate, M.W. 5.000 MFCD00025910 (CAS 58320-73-3), molecular formula C10H14O4S and molecular weight 230.28 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 58320-73-3 Polyethylene glycol monomethyl ether p-toluenesulfonate, M.W. 5.000 MFCD00025910 (C10H14O4S) 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 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 230.28 g/mol, it falls into the medium-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.
