Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Diisooctyl phthalate.
CATO supplies Diisooctyl phthalate (CAS 27554-26-3), a certified reference material (molecular formula C24H38O4, MW 390.28 g/mol) for analytical method development and quality control.
Owing to a steroid core, a hydroxyl group, an ether linkage, Diisooctyl phthalate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 390.28 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Diisooctyl 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.
