Description

Compared with other compounds in its class, the molecular weight of 126.14 g/mol gives 71189-23-6 A837108 sodium 3-[[2-(4-hydroxyphenyl)sulfonyl-5-oxidanyl-phenyl]methyl]naphthalene-2-sulfonate sodium 3-[[5-hydroxy-2-(4-hydroxyphenyl)sulfonylphenyl]methyl]-2-naphthalenesulfonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

71189-23-6 A837108 sodium 3-[[2-(4-hydroxyphenyl)sulfonyl-5-oxidanyl-phenyl]methyl]naphthalene-2-sulfonate sodium 3-[[5-hydroxy-2-(4-hydroxyphenyl)sulfonylphenyl]methyl]-2-naphthalenesulfonate (CAS 71189-23-6), molecular formula C4H2N2OS and molecular weight 126.14 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 71189-23-6 A837108 sodium 3-[[2-(4-hydroxyphenyl)sulfonyl-5-oxidanyl-phenyl]methyl]naphthalene-2-sulfonate sodium 3-[[5-hydroxy-2-(4-hydroxyphenyl)sulfonylphenyl]methyl]-2-naphthalenesulfonate is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 126.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
