Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Tert-butyl 4-(3-cyclohexylureido)piperidine-1-carboxylate.
Tert-butyl 4-(3-cyclohexylureido)piperidine-1-carboxylate (CAS 950184-31-3) is a high-purity analytical reference standard with the molecular formula C17H31N3O3 and a molecular weight of 325.45 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, Tert-butyl 4-(3-cyclohexylureido)piperidine-1-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 325.45 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
