Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 627.81 g/mol gives 1H-Benzimidazolesulfonic acid, 2-heptadecyl-1-[(3-sulfophenyl)methyl]-, sodium salt (1:2) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1H-Benzimidazolesulfonic acid, 2-heptadecyl-1-[(3-sulfophenyl)methyl]-, sodium salt (1:2) (CAS 68228-07-9) is a high-purity analytical reference standard with the molecular formula C31H44N2O6S2Na and a molecular weight of 627.81 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 1H-Benzimidazolesulfonic acid, 2-heptadecyl-1-[(3-sulfophenyl)methyl]-, sodium salt (1:2) is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 627.81 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).
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.
CATO manufactures 1H-Benzimidazolesulfonic acid, 2-heptadecyl-1-[(3-sulfophenyl)methyl]-, sodium salt (1:2) under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
