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 5-Fluoro-1H-imidazole-4-carbohydrazide.
CATO supplies 5-Fluoro-1H-imidazole-4-carbohydrazide (CAS 330953-77-0), a certified reference material (molecular formula C4H5FN4O, MW 144.11 g/mol) for analytical method development and quality control.
Owing to an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 5-Fluoro-1H-imidazole-4-carbohydrazide is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 144.11 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
