Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 237.20 g/mol gives Sodium 3-acetamidobenzene-1-sulfonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Sodium 3-acetamidobenzene-1-sulfonate (CAS 1080-11-1), a certified reference material (molecular formula C8H8NO4SNa, MW 237.20 g/mol) for analytical method development and quality control.
The molecular framework of Sodium 3-acetamidobenzene-1-sulfonate (C8H8NO4SNa) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
As a certified reference material (CRM), Sodium 3-acetamidobenzene-1-sulfonate 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.
