Chemical Structure
Description
The occurrence of Phosphoric acid, dibutyl ester, potassium salt is closely related to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Phosphoric acid, dibutyl ester, potassium salt (CAS 25238-98-6), a certified reference material (molecular formula C8H18O4PK, MW 248.30 g/mol) for analytical method development and quality control.
The molecular framework of Phosphoric acid, dibutyl ester, potassium salt (C8H18O4PK) is characterized by a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.
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 Phosphoric acid, dibutyl ester, potassium salt 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.
