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 (3S)-1,2,3,4-Tetrahydro-6,7-dimethoxy-3-isoquinolinecarboxylic Acid.
(3S)-1,2,3,4-Tetrahydro-6,7-dimethoxy-3-isoquinolinecarboxylic Acid (CAS 103733-66-0) is a high-purity analytical reference standard with the molecular formula C12H15NO4 and a molecular weight of 237.25 g/mol.
The molecular framework of (3S)-1,2,3,4-Tetrahydro-6,7-dimethoxy-3-isoquinolinecarboxylic Acid (C12H15NO4) is characterized by an amino-acid-derived structure, an amide 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), (3S)-1,2,3,4-Tetrahydro-6,7-dimethoxy-3-isoquinolinecarboxylic 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.
