Description

513-49-5 Z192XWH21O 2-Butanamine, (S)- 2-Butanamine, (S)- (9CI) 2-Butanamine, (2S)- (S)-sec-Butylamine (S)-2-Aminobutane S-2-Butylamine (+)-2-Butylamine EINECS 208-164-7 UNII-Z192XWH21O sec-Butylamine, (S)- sec-Butylamine (CAS 513-49-5), molecular formula C4H11N and molecular weight 73.14 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C4H11N, 513-49-5 Z192XWH21O 2-Butanamine, (S)- 2-Butanamine, (S)- (9CI) 2-Butanamine, (2S)- (S)-sec-Butylamine (S)-2-Aminobutane S-2-Butylamine (+)-2-Butylamine EINECS 208-164-7 UNII-Z192XWH21O sec-Butylamine, (S)- sec-Butylamine contains an organic framework; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 73.14 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.
