Chemical Structure
Description
Sodium pentyl sulfate (CAS 556-76-3) is a high-purity analytical reference standard with the molecular formula C5H11O4SNa and a molecular weight of 190.19 g/mol.
Based on its molecular formula C5H11O4SNa, Sodium pentyl sulfate contains a carbohydrate-derived structure, a sulfone group; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 190.19 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.
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.
CATO manufactures Sodium pentyl sulfate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
