Description

The occurrence of 833-66-9 4IDS1OY3TA Potassium 6-hydroxy-2-naphthalenesulfonate Potassium 6-hydroxynaphthalene-2-sulphonate 2-Naphthalenesulfonic acid, 6-hydroxy-, potassium salt (1:1) 2-Naphthalenesulfonic acid, 6-hydroxy-, monopotassium salt EINECS 212-631-0 Schaeffer's acid, monopotassium salt UNII-4IDS1OY3TA is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 833-66-9 4IDS1OY3TA Potassium 6-hydroxy-2-naphthalenesulfonate Potassium 6-hydroxynaphthalene-2-sulphonate 2-Naphthalenesulfonic acid, 6-hydroxy-, potassium salt (1:1) 2-Naphthalenesulfonic acid, 6-hydroxy-, monopotassium salt EINECS 212-631-0 Schaeffer's acid, monopotassium salt UNII-4IDS1OY3TA (CAS 833-66-9), a certified reference material (molecular formula C10H17O4SK, MW 272.40 g/mol) for analytical method development and quality control.

Structurally, 833-66-9 4IDS1OY3TA Potassium 6-hydroxy-2-naphthalenesulfonate Potassium 6-hydroxynaphthalene-2-sulphonate 2-Naphthalenesulfonic acid, 6-hydroxy-, potassium salt (1:1) 2-Naphthalenesulfonic acid, 6-hydroxy-, monopotassium salt EINECS 212-631-0 Schaeffer's acid, monopotassium salt UNII-4IDS1OY3TA (C10H17O4SK) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.5, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 272.40 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.
