Chemical Structure

1-Butyl-3-(1-ethynylcyclohexyl)urea CAS 92107-11-4 chemical structure

Description

1-Butyl-3-(1-ethynylcyclohexyl)urea (CAS 92107-11-4) is a high-purity analytical reference standard with the molecular formula C13H22N2O and a molecular weight of 222.33 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 1-Butyl-3-(1-ethynylcyclohexyl)urea is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 222.33 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.
