Description
Compared with other compounds in its class, the molecular weight of 224.64 g/mol gives 3-(1,3-Benzodioxol-5-yl)-1H-pyrazole hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-(1,3-Benzodioxol-5-yl)-1H-pyrazole hydrochloride (CAS 1269199-66-7), a certified reference material (molecular formula C10H8N2O2HCl, MW 224.64 g/mol) for analytical method development and quality control.
The molecular framework of 3-(1,3-Benzodioxol-5-yl)-1H-pyrazole hydrochloride (C10H8N2O2HCl) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 3-(1,3-Benzodioxol-5-yl)-1H-pyrazole hydrochloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
