Description
Compared with other compounds in its class, the molecular weight of 283.12 g/mol gives Ethyl 6-bromo-4-methylpyrazolo[1,5-a]pyridine-2-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Ethyl 6-bromo-4-methylpyrazolo[1,5-a]pyridine-2-carboxylate (CAS 1822835-40-4), a certified reference material (molecular formula C11H11BrN2O2, MW 283.12 g/mol) for analytical method development and quality control.
The molecular framework of Ethyl 6-bromo-4-methylpyrazolo[1,5-a]pyridine-2-carboxylate (C11H11BrN2O2) 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 its high hydrophobicity (logP), 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 Ethyl 6-bromo-4-methylpyrazolo[1,5-a]pyridine-2-carboxylate 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.
