6-(Pyridin-3-yl)imidazo[2,1-b]thiazole-5-carbaldehyde CAS 139359-79-8

Description

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.

6-(Pyridin-3-yl)imidazo[2,1-b]thiazole-5-carbaldehyde (CAS 139359-79-8) is a high-purity analytical reference standard with the molecular formula C11H7N3OS and a molecular weight of 229.26 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 6-(Pyridin-3-yl)imidazo[2,1-b]thiazole-5-carbaldehyde is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 229.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
