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 1,2-Diisopropyl-2,3-dihydro-1H-pyrazole.
1,2-Diisopropyl-2,3-dihydro-1H-pyrazole (CAS 545342-29-8), molecular formula C9H18N2 and molecular weight 154.25 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1,2-Diisopropyl-2,3-dihydro-1H-pyrazole (C9H18N2) is characterized by a nitrile group. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 1,2-Diisopropyl-2,3-dihydro-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.
