Chemical Structure
Description
The molecular framework of 5-(3-Chloropropyl)-1,3-dimethyl-1h-pyrazole (C8H13ClN2) is characterized by a nitrile group, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
5-(3-Chloropropyl)-1,3-dimethyl-1h-pyrazole (CAS 1488098-80-1) is a high-purity analytical reference standard with the molecular formula C8H13ClN2 and a molecular weight of 172.66 g/mol.
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 manufactures 5-(3-Chloropropyl)-1,3-dimethyl-1h-pyrazole 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.
