Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 66967-01-9 (3R,4S)-N-t-Butyloxycarbonyl-statine, (3R,4S)-3-Hydroxy-4-Boc-amino-6-methyl-heptanoic acid MFCD00063179.

66967-01-9 (3R,4S)-N-t-Butyloxycarbonyl-statine, (3R,4S)-3-Hydroxy-4-Boc-amino-6-methyl-heptanoic acid MFCD00063179 (CAS 66967-01-9), molecular formula C13H25NO5 and molecular weight 275.34 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C13H25NO5, 66967-01-9 (3R,4S)-N-t-Butyloxycarbonyl-statine, (3R,4S)-3-Hydroxy-4-Boc-amino-6-methyl-heptanoic acid MFCD00063179 contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 275.34 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
