5-[4-(1,2-BEnzisothiazol-3-yl)piperazin-1-yl]-5-oxopentanoic acid CAS 2108519-47-5

Description

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.

CATO supplies 5-[4-(1,2-BEnzisothiazol-3-yl)piperazin-1-yl]-5-oxopentanoic acid (CAS 2108519-47-5), a certified reference material (molecular formula C16H19N3O3S, MW 333.41 g/mol) for analytical method development and quality control.

Structurally, 5-[4-(1,2-BEnzisothiazol-3-yl)piperazin-1-yl]-5-oxopentanoic acid (C16H19N3O3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 333.41 g/mol, it falls into the moderately-high-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.

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.
