<I>N,N′</I>-bis-Boc-1<I>H</I>-1-guanidinopyrazole CAS 152120-54-2 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 314.38 g/mol gives <I>N,N′</I>-bis-Boc-1<I>H</I>-1-guanidinopyrazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

<I>N,N′</I>-bis-Boc-1<I>H</I>-1-guanidinopyrazole (CAS 152120-54-2), molecular formula C14H26N4O4 and molecular weight 314.38 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, <I>N,N′</I>-bis-Boc-1<I>H</I>-1-guanidinopyrazole is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 314.38 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.

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.
