N'-((2-Hydroxynaphthalen-1-yl)methylene)-3-methyl-1-phenyl-1H-thieno[2,3-c]pyrazole-5-carbohydrazide CAS 296262-01-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N'-((2-Hydroxynaphthalen-1-yl)methylene)-3-methyl-1-phenyl-1H-thieno[2,3-c]pyrazole-5-carbohydrazide.

CATO supplies N'-((2-Hydroxynaphthalen-1-yl)methylene)-3-methyl-1-phenyl-1H-thieno[2,3-c]pyrazole-5-carbohydrazide (CAS 296262-01-6), a certified reference material (molecular formula C24H18N4O2S, MW 426.49 g/mol) for analytical method development and quality control.

Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, N'-((2-Hydroxynaphthalen-1-yl)methylene)-3-methyl-1-phenyl-1H-thieno[2,3-c]pyrazole-5-carbohydrazide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 426.49 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).

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.
