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 79232-66-9 Butanoic acid, 4-bromo-2-(methoxyimino)-3-oxo-,(2Z)-.
CATO supplies 79232-66-9 Butanoic acid, 4-bromo-2-(methoxyimino)-3-oxo-,(2Z)- (CAS 79232-66-9), a certified reference material (molecular formula C5H6BrNO4, MW 224.01 g/mol) for analytical method development and quality control.
Owing to a carbohydrate-derived structure, an amide group, bromine substitution, 79232-66-9 Butanoic acid, 4-bromo-2-(methoxyimino)-3-oxo-,(2Z)- is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 224.01 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 79232-66-9 Butanoic acid, 4-bromo-2-(methoxyimino)-3-oxo-,(2Z)- 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.
