Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(5-chloropentyl)-1H-pyrazole hydrochloride.
CATO supplies 1-(5-chloropentyl)-1H-pyrazole hydrochloride (CAS 1251923-16-6), a certified reference material (molecular formula C8H13ClN2HCl, MW 209.11 g/mol) for analytical method development and quality control.
1-(5-chloropentyl)-1H-pyrazole hydrochloride (C8H13ClN2HCl) 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.
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.
As a certified reference material (CRM), 1-(5-chloropentyl)-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.
