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-isopropylpyrazole-3-carbonyl chloride.
CATO supplies 1-isopropylpyrazole-3-carbonyl chloride (CAS 1435244-63-5), a certified reference material (molecular formula C7H13ClN2O, MW 176.64 g/mol) for analytical method development and quality control.
The molecular framework of 1-isopropylpyrazole-3-carbonyl chloride (C7H13ClN2O) is characterized by an amide group, a hydroxyl group, an ether linkage, 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.
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), 1-isopropylpyrazole-3-carbonyl chloride 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.
