N-(4-chloro-2-methylphenyl)-4-hydrazinyl-4-oxobutanamide CAS 443863-35-2

Description

The occurrence of N-(4-chloro-2-methylphenyl)-4-hydrazinyl-4-oxobutanamide is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

N-(4-chloro-2-methylphenyl)-4-hydrazinyl-4-oxobutanamide (CAS 443863-35-2), molecular formula C11H14ClN3O2 and molecular weight 255.70 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, N-(4-chloro-2-methylphenyl)-4-hydrazinyl-4-oxobutanamide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 255.70 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

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.
