Chemical Structure
Description
CATO supplies Bis(3-methylpentyl) Phthalate (CAS 911235-36-4), a certified reference material (molecular formula C20H30O4, MW 334.45 g/mol) for analytical method development and quality control.
Based on its molecular formula C20H30O4, Bis(3-methylpentyl) Phthalate contains a steroid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 334.45 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), Bis(3-methylpentyl) 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.
