Chemical Structure

Monobutyl Phthalate Acyl-β-D-glucuronide CAS 85209-81-0 chemical structure

Description

Monobutyl Phthalate Acyl-β-D-glucuronide (CAS 85209-81-0), molecular formula C18H22O10 and molecular weight 398.36 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C18H22O10, Monobutyl Phthalate Acyl-β-D-glucuronide contains a flavonoid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 398.36 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
