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-(5-Ethyl-1,3,4-thiadiazol-2-yl)-4-(pyrrolidin-1-ylsulfonyl)benzamide.
N-(5-Ethyl-1,3,4-thiadiazol-2-yl)-4-(pyrrolidin-1-ylsulfonyl)benzamide (CAS 577752-93-3), molecular formula C15H18N4O3S2 and molecular weight 366.46 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, N-(5-Ethyl-1,3,4-thiadiazol-2-yl)-4-(pyrrolidin-1-ylsulfonyl)benzamide (C15H18N4O3S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 366.46 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
