Chemical Structure
Description
The occurrence of (4-Bromo-3-methoxyphenyl)hydrazine hydrochloride is closely related to an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(4-Bromo-3-methoxyphenyl)hydrazine hydrochloride (CAS 262851-33-2) is a high-purity analytical reference standard with the molecular formula C7H9BrN2OHCl and a molecular weight of 253.52 g/mol.
(4-Bromo-3-methoxyphenyl)hydrazine hydrochloride (C7H9BrN2OHCl) contains an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), (4-Bromo-3-methoxyphenyl)hydrazine hydrochloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
