5-Methyl-1-(2-(pyridin-2-ylmethyl)-1,2,3,4-tetrahydroisoquinolin-5-yl)-1h-1,2,3-triazole-4-carboxylic acid dihydrochloride CAS 1334146-66-5 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 5-Methyl-1-(2-(pyridin-2-ylmethyl)-1,2,3,4-tetrahydroisoquinolin-5-yl)-1h-1,2,3-triazole-4-carboxylic acid dihydrochloride.

5-Methyl-1-(2-(pyridin-2-ylmethyl)-1,2,3,4-tetrahydroisoquinolin-5-yl)-1h-1,2,3-triazole-4-carboxylic acid dihydrochloride (CAS 1334146-66-5) is a high-purity analytical reference standard with the molecular formula C19H19N5O2HCl and a molecular weight of 385.85 g/mol.

Structurally, 5-Methyl-1-(2-(pyridin-2-ylmethyl)-1,2,3,4-tetrahydroisoquinolin-5-yl)-1h-1,2,3-triazole-4-carboxylic acid dihydrochloride (C19H19N5O2HCl) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 385.85 g/mol, it falls into the moderately-high-molecular-weight range. 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.
