Chemical Structure

Tripentyl phosphate CAS 2528-38-3 chemical structure

Description

Tripentyl phosphate (CAS 2528-38-3), molecular formula C15H33O4P and molecular weight 308.39 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, Tripentyl phosphate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 308.39 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

CATO manufactures Tripentyl 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.
