Chemical Structure
Description
4-(3-Methyl-5-isoxazolyl)piperidine hydrochloride (CAS 1401425-44-2) is a high-purity analytical reference standard with the molecular formula C9H14N2OHCl and a molecular weight of 202.68 g/mol.
Owing to an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 4-(3-Methyl-5-isoxazolyl)piperidine hydrochloride is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 202.68 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
