{1-[(1,3-dimethyl-1H-pyrazol-4-yl)sulfonyl]piperidin-4-yl}acetic acid CAS 1171599-18-0

Description

{1-[(1,3-dimethyl-1H-pyrazol-4-yl)sulfonyl]piperidin-4-yl}acetic acid (CAS 1171599-18-0), molecular formula C12H19N3O4S and molecular weight 301.36 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, {1-[(1,3-dimethyl-1H-pyrazol-4-yl)sulfonyl]piperidin-4-yl}acetic acid (C12H19N3O4S) 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 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 301.36 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
