Chemical Structure

1189685-87-7 N,N'-Di-(n-octyl-d17)-3,3'-dithiodipropionamide N-(1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,8-heptadecadeuteriooctyl)-3-[[3-(1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,8-heptadecadeuteriooctylamino)-3-oxopropyl]disulfanyl]propanamide CAS 1189685-87-7 chemical structure

Description

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.

1189685-87-7 N,N'-Di-(n-octyl-d17)-3,3'-dithiodipropionamide N-(1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,8-heptadecadeuteriooctyl)-3-[[3-(1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,8-heptadecadeuteriooctylamino)-3-oxopropyl]disulfanyl]propanamide (CAS 1189685-87-7) is a high-purity analytical reference standard with the molecular formula C22H44N2O2S2 and a molecular weight of 432.73 g/mol.

The molecular framework of 1189685-87-7 N,N'-Di-(n-octyl-d17)-3,3'-dithiodipropionamide N-(1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,8-heptadecadeuteriooctyl)-3-[[3-(1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,8-heptadecadeuteriooctylamino)-3-oxopropyl]disulfanyl]propanamide (C22H44N2O2S2) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
