Description

The occurrence of 62625-22-3 Benzoic acid, 2-(1-(2-hydroxy-5-sulfophenyl)-3-phenyl-5-formazano)-, monosodium salt Sodium hydrogen 2-(1-(2-hydroxy-5-sulphonatophenyl)-3-phenyl-5-formazano)benzoate Benzoic acid, 2-(2-((2-(2-hydroxy-5-sulfophenyl)diazenyl)phenylmethylene)hydrazinyl)-, sodium salt (1:1) Benzoic acid, 2-((((2-hydroxy-5-sulfophenyl)azo)phenylmethylene)hydrazino)-, monosodium salt EINECS 263-651-1 is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

62625-22-3 Benzoic acid, 2-(1-(2-hydroxy-5-sulfophenyl)-3-phenyl-5-formazano)-, monosodium salt Sodium hydrogen 2-(1-(2-hydroxy-5-sulphonatophenyl)-3-phenyl-5-formazano)benzoate Benzoic acid, 2-(2-((2-(2-hydroxy-5-sulfophenyl)diazenyl)phenylmethylene)hydrazinyl)-, sodium salt (1:1) Benzoic acid, 2-((((2-hydroxy-5-sulfophenyl)azo)phenylmethylene)hydrazino)-, monosodium salt EINECS 263-651-1 (CAS 62625-22-3), molecular formula C20H33N4O6SNa and molecular weight 480.56 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 62625-22-3 Benzoic acid, 2-(1-(2-hydroxy-5-sulfophenyl)-3-phenyl-5-formazano)-, monosodium salt Sodium hydrogen 2-(1-(2-hydroxy-5-sulphonatophenyl)-3-phenyl-5-formazano)benzoate Benzoic acid, 2-(2-((2-(2-hydroxy-5-sulfophenyl)diazenyl)phenylmethylene)hydrazinyl)-, sodium salt (1:1) Benzoic acid, 2-((((2-hydroxy-5-sulfophenyl)azo)phenylmethylene)hydrazino)-, monosodium salt EINECS 263-651-1 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 480.56 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
