Description

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, (2R)-N1-[(1S)-2,2-Dimethyl-1-({[(1R)-1-phenylethyl]amino}carbonyl)propyl]-2-{3-[(3-methyl-4-phenyl)-phenyl]propyl}-(N4-hydroxy)butanediamide (2R)-N1-[(1S)-2,2-Dimethyl-1-[[[(1R)-1-phenylethyl]amino]carbonyl]propyl]-N4-hydroxy-2-[3-(2-methyl[1,1'-biphenyl]-4-yl)propyl]butanediamide 230961-08-7 PF-03890101 UK 356618 UK-356,618 UK-356618 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 575.87 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

(2R)-N1-[(1S)-2,2-Dimethyl-1-({[(1R)-1-phenylethyl]amino}carbonyl)propyl]-2-{3-[(3-methyl-4-phenyl)-phenyl]propyl}-(N4-hydroxy)butanediamide (2R)-N1-[(1S)-2,2-Dimethyl-1-[[[(1R)-1-phenylethyl]amino]carbonyl]propyl]-N4-hydroxy-2-[3-(2-methyl[1,1'-biphenyl]-4-yl)propyl]butanediamide 230961-08-7 PF-03890101 UK 356618 UK-356,618 UK-356618 (CAS 230961-08-7), molecular formula C34H61N3O4 and molecular weight 575.87 g/mol, is a CATO reference standard with documented purity and traceability.

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.

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.
