Chemical Structure
Description
Structurally, 5323-87-5 AR-1K6976 n-ethyl-n-(3-(trimethoxysilyl)propyl)-1,1,2,2,3,3,4,4,5,5,6,6,7,7,7-pentadecafluoroheptanesulfonamide (C8H12O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 140.18 g/mol, it falls into the low-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).
5323-87-5 AR-1K6976 n-ethyl-n-(3-(trimethoxysilyl)propyl)-1,1,2,2,3,3,4,4,5,5,6,6,7,7,7-pentadecafluoroheptanesulfonamide (CAS 5323-87-5), molecular formula C8H12O2 and molecular weight 140.18 g/mol, is a CATO reference standard with documented purity and traceability.
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.
