Description

Structurally, 56W89FBX3E 91-21-4 1,2,3,4-Tetrahydroisoquinoline Isoquinoline, 1,2,3,4-tetrahydro- 5-20-06-00320 (Beilstein Handbook Reference) AI3-15931 BRN 0116156 EINECS 202-050-0 NSC 15312 Tetrahydroisoquinoline UNII-56W89FBX3E EC 202-050-0 (C9H17N) contains a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 139.24 g/mol, it falls into the low-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

CATO supplies 56W89FBX3E 91-21-4 1,2,3,4-Tetrahydroisoquinoline Isoquinoline, 1,2,3,4-tetrahydro- 5-20-06-00320 (Beilstein Handbook Reference) AI3-15931 BRN 0116156 EINECS 202-050-0 NSC 15312 Tetrahydroisoquinoline UNII-56W89FBX3E EC 202-050-0 (CAS 91-21-4), a certified reference material (molecular formula C9H17N, MW 139.24 g/mol) for analytical method development and quality control.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
