Description
CATO manufactures (R)-1-(Pyridin-2-ylmethyl)-3-(pyrrolidin-3-yl)urea hydrochloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
CATO supplies (R)-1-(Pyridin-2-ylmethyl)-3-(pyrrolidin-3-yl)urea hydrochloride (CAS 1439894-53-7), a certified reference material (molecular formula C11H16N4OHCl, MW 256.73 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, (R)-1-(Pyridin-2-ylmethyl)-3-(pyrrolidin-3-yl)urea hydrochloride is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 256.73 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
