Chemical Structure
Description
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 supplies 1-(7-Chloro-3-iodo-2-methylpyrazolo[1,5-a]pyrimidin-5-yl)ethan-1-one (CAS 2387601-56-9), a certified reference material (molecular formula C9H7ClIN3O, MW 335.53 g/mol) for analytical method development and quality control.
The molecular framework of 1-(7-Chloro-3-iodo-2-methylpyrazolo[1,5-a]pyrimidin-5-yl)ethan-1-one (C9H7ClIN3O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/iodine 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures 1-(7-Chloro-3-iodo-2-methylpyrazolo[1,5-a]pyrimidin-5-yl)ethan-1-one 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.
