Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 207.23 g/mol gives 7-Methoxy-1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
7-Methoxy-1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid (CAS 98698-26-1), molecular formula C11H13NO3 and molecular weight 207.23 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 7-Methoxy-1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid (C11H13NO3) 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 its high hydrophobicity (logP), 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 7-Methoxy-1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid 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.
