Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (S)-2-((4-Ethoxyphenyl)sulfonyl)-1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid.
CATO supplies (S)-2-((4-Ethoxyphenyl)sulfonyl)-1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid (CAS 1212488-34-0), a certified reference material (molecular formula C18H19NO5S, MW 361.41 g/mol) for analytical method development and quality control.
The molecular framework of (S)-2-((4-Ethoxyphenyl)sulfonyl)-1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid (C18H19NO5S) is characterized by a flavonoid core, 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), (S)-2-((4-Ethoxyphenyl)sulfonyl)-1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid 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.
