Chemical Structure
Description
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.
CATO supplies 5-[(2R)-pyrrolidin-2-yl]-2H-1,2,3,4-tetrazole hydrochloride (CAS 1956437-95-8), a certified reference material (molecular formula C5H9N5HCl, MW 175.62 g/mol) for analytical method development and quality control.
5-[(2R)-pyrrolidin-2-yl]-2H-1,2,3,4-tetrazole hydrochloride (C5H9N5HCl) contains a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures 5-[(2R)-pyrrolidin-2-yl]-2H-1,2,3,4-tetrazole 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.
