Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 350.47 g/mol gives Trihexyl Phosphate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Trihexyl Phosphate (CAS 2528-39-4), molecular formula C18H39O4P and molecular weight 350.47 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Trihexyl Phosphate (C18H39O4P) contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of -0.5, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 350.47 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Trihexyl Phosphate 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.
