Chemical Structure
Description
As a certified reference material (CRM), 4-Chloro-3-ethylbenzenethiol 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.
CATO supplies 4-Chloro-3-ethylbenzenethiol (CAS 1314935-29-9), a certified reference material (molecular formula C8H9ClS, MW 172.68 g/mol) for analytical method development and quality control.
4-Chloro-3-ethylbenzenethiol (C8H9ClS) contains sulfur-containing functionality, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
