Description

Based on its molecular formula C9H18O2, 79AS95G5J0 5921-83-5 3-Heptanyl acetate UNII-79AS95G5J0 FEMA No. 3980 (+/-)-heptan-3-yl acetate 1-Ethylpentyl acetate 3-Heptanol, 3-acetate 3-Heptanol, acetate Hept-3-yl ethanoate Heptan-3-yl acetate, (+/-)- contains 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 158.24 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

79AS95G5J0 5921-83-5 3-Heptanyl acetate UNII-79AS95G5J0 FEMA No. 3980 (+/-)-heptan-3-yl acetate 1-Ethylpentyl acetate 3-Heptanol, 3-acetate 3-Heptanol, acetate Hept-3-yl ethanoate Heptan-3-yl acetate, (+/-)- (CAS 5921-83-5), molecular formula C9H18O2 and molecular weight 158.24 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.
