Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 278.34 g/mol gives Phthalic Acid, Bis-Iso-Butyl Ester distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Phthalic Acid, Bis-Iso-Butyl Ester (CAS 84-69-5), a certified reference material (molecular formula C16H22O4, MW 278.34 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, Phthalic Acid, Bis-Iso-Butyl Ester is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 278.34 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.
CATO manufactures Phthalic Acid, Bis-Iso-Butyl Ester 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.
