Chemical Structure

1-Methyl-2-oxo-1,2,3,4-tetrahydroquinoline-6-sulfonyl chloride CAS 140618-96-8 chemical structure

Description

The molecular framework of 1-Methyl-2-oxo-1,2,3,4-tetrahydroquinoline-6-sulfonyl chloride (C10H10ClNO3S) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

1-Methyl-2-oxo-1,2,3,4-tetrahydroquinoline-6-sulfonyl chloride (CAS 140618-96-8), molecular formula C10H10ClNO3S and molecular weight 259.71 g/mol, is a CATO reference standard with documented purity and traceability.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 1-Methyl-2-oxo-1,2,3,4-tetrahydroquinoline-6-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.
