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 Methyl (S)-7-hydroxy-1,2,3,4-tetrahydroisoquinoline-3-carboxylate hydrochloride.
CATO supplies Methyl (S)-7-hydroxy-1,2,3,4-tetrahydroisoquinoline-3-carboxylate hydrochloride (CAS 178205-92-0), a certified reference material (molecular formula C11H13NO3HCl, MW 243.69 g/mol) for analytical method development and quality control.
Based on its molecular formula C11H13NO3HCl, Methyl (S)-7-hydroxy-1,2,3,4-tetrahydroisoquinoline-3-carboxylate hydrochloride contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 243.69 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 Methyl (S)-7-hydroxy-1,2,3,4-tetrahydroisoquinoline-3-carboxylate hydrochloride 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.
