Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Bromo-1-butyl-1H-pyrazole-3-carbaldehyde.
4-Bromo-1-butyl-1H-pyrazole-3-carbaldehyde (CAS 1708288-53-2), molecular formula C8H11BrN2O and molecular weight 231.09 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution, 4-Bromo-1-butyl-1H-pyrazole-3-carbaldehyde is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 231.09 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 4-Bromo-1-butyl-1H-pyrazole-3-carbaldehyde 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.
