Chemical Structure
Description
(3-Bromo-1-methyl-1H-pyrazol-5-yl)dimethylphosphine oxide (CAS 2903427-64-3), molecular formula C6H10BrN2OP and molecular weight 237.03 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (3-Bromo-1-methyl-1H-pyrazol-5-yl)dimethylphosphine oxide (C6H10BrN2OP) is characterized by an amide group, organophosphorus functionality, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 (3-Bromo-1-methyl-1H-pyrazol-5-yl)dimethylphosphine oxide 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.
