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 N-(1-(1-(4-Ethylphenyl)-1H-1,2,3-triazole-4-carbonyl)piperidin-4-yl)-2-(thiophen-2-yl)acetamide.
CATO supplies N-(1-(1-(4-Ethylphenyl)-1H-1,2,3-triazole-4-carbonyl)piperidin-4-yl)-2-(thiophen-2-yl)acetamide (CAS 1251592-29-6), a certified reference material (molecular formula C22H25N5O2S, MW 423.53 g/mol) for analytical method development and quality control.
Structurally, N-(1-(1-(4-Ethylphenyl)-1H-1,2,3-triazole-4-carbonyl)piperidin-4-yl)-2-(thiophen-2-yl)acetamide (C22H25N5O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 423.53 g/mol, it falls into the moderately-high-molecular-weight range. 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.
