Isopropyl Palmitate CAS 142-91-6 chemical structure

Description

CATO supplies Isopropyl Palmitate (CAS 142-91-6), a certified reference material (molecular formula C19H38O2, MW 298.50 g/mol) for analytical method development and quality control.

Based on its molecular formula C19H38O2, Isopropyl Palmitate 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 298.50 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

As a certified reference material (CRM), Isopropyl Palmitate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
