Chemical Structure
Description
(R)-5-(1,2-dithiolan-3-yl)-N-(2,5,8,11-tetraoxatridecan-13-yl)pentanamide (CAS 1334172-66-5) is a high-purity analytical reference standard with the molecular formula C17H33NO5S2 and a molecular weight of 395.58 g/mol.
(R)-5-(1,2-dithiolan-3-yl)-N-(2,5,8,11-tetraoxatridecan-13-yl)pentanamide (C17H33NO5S2) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
