Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 201.65 g/mol gives Dopamine Impurity 49 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Dopamine Impurity 49 (CAS 925680-03-1), molecular formula C9H12ClNO2 and molecular weight 201.65 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, chlorine substitution, Dopamine Impurity 49 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 201.65 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 Dopamine Impurity 49 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.
