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 1H-Pyrazole, 4-bromo-3-nitro-1-(tetrahydro-2H-pyran-2-yl)-.
1H-Pyrazole, 4-bromo-3-nitro-1-(tetrahydro-2H-pyran-2-yl)- (CAS 1235407-33-6) is a high-purity analytical reference standard with the molecular formula C8H10BrN3O3 and a molecular weight of 276.09 g/mol.
1H-Pyrazole, 4-bromo-3-nitro-1-(tetrahydro-2H-pyran-2-yl)- (C8H10BrN3O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 1H-Pyrazole, 4-bromo-3-nitro-1-(tetrahydro-2H-pyran-2-yl)- 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.
