5-(N-Ethylacetamido)naphthalene-1-sulfonyl chloride CAS 728864-89-9

Description

As a certified reference material (CRM), 5-(N-Ethylacetamido)naphthalene-1-sulfonyl chloride 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.

5-(N-Ethylacetamido)naphthalene-1-sulfonyl chloride (CAS 728864-89-9), molecular formula C14H14ClNO3S and molecular weight 311.78 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 5-(N-Ethylacetamido)naphthalene-1-sulfonyl chloride (C14H14ClNO3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
