3-Chloro-4-(4-methoxypiperidin-1-yl)-1,2,5-thiadiazole CAS 1157572-09-2

Description

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, 3-Chloro-4-(4-methoxypiperidin-1-yl)-1,2,5-thiadiazole is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 233.72 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

3-Chloro-4-(4-methoxypiperidin-1-yl)-1,2,5-thiadiazole (CAS 1157572-09-2) is a high-purity analytical reference standard with the molecular formula C8H12ClN3OS and a molecular weight of 233.72 g/mol.

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.
