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 diethyl 5-bromopyrazolo[1,5-a]pyridine-2,3-dicarboxylate.
CATO supplies diethyl 5-bromopyrazolo[1,5-a]pyridine-2,3-dicarboxylate (CAS 2809036-35-7), a certified reference material (molecular formula C13H21BrN2O4, MW 349.22 g/mol) for analytical method development and quality control.
The molecular framework of diethyl 5-bromopyrazolo[1,5-a]pyridine-2,3-dicarboxylate (C13H21BrN2O4) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures diethyl 5-bromopyrazolo[1,5-a]pyridine-2,3-dicarboxylate 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.
