1,3-Dimethyl-5-(piperazin-1-yl)-1h-pyrazole-4-carbonitrile CAS 1339479-03-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,3-Dimethyl-5-(piperazin-1-yl)-1h-pyrazole-4-carbonitrile.

1,3-Dimethyl-5-(piperazin-1-yl)-1h-pyrazole-4-carbonitrile (CAS 1339479-03-6), molecular formula C10H15N5 and molecular weight 205.26 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 1,3-Dimethyl-5-(piperazin-1-yl)-1h-pyrazole-4-carbonitrile (C10H15N5) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 205.26 g/mol, it falls into the medium-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.

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.
