Monooctyl Phthalate CAS 5393-19-1

Description

Compared with other compounds in its class, the molecular weight of 278.34 g/mol gives Monooctyl Phthalate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Monooctyl Phthalate (CAS 5393-19-1), molecular formula C16H22O4 and molecular weight 278.34 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C16H22O4, Monooctyl Phthalate contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 278.34 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

As a certified reference material (CRM), Monooctyl Phthalate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
