Chemical Structure
Description
The molecular framework of 1,6,7,8-tetrahydrocyclopenta[g]indole-3-sulfonyl chloride (C11H18ClNO2S) is characterized by an amide group, a sulfone group, a carboxylic acid 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.
CATO supplies 1,6,7,8-tetrahydrocyclopenta[g]indole-3-sulfonyl chloride (CAS 2231234-23-2), a certified reference material (molecular formula C11H18ClNO2S, MW 263.78 g/mol) for analytical method development and quality control.
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 1,6,7,8-tetrahydrocyclopenta[g]indole-3-sulfonyl chloride 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.
