rac Mono(ethylhexyl) Phthalate-d4 CAS 1276197-22-8

Description

Compared with other compounds in its class, the molecular weight of 282.37 g/mol gives rac Mono(ethylhexyl) Phthalate-d4 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

rac Mono(ethylhexyl) Phthalate-d4 (CAS 1276197-22-8), molecular formula C16H18D4O4 and molecular weight 282.37 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of rac Mono(ethylhexyl) Phthalate-d4 (C16H18D4O4) is characterized by deuterium isotope labeling, a flavonoid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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 rac Mono(ethylhexyl) Phthalate-d4 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.
