Chemical Structure

Mono(2- (2- carboxyethyl) - 3- hydroxybutyl) Phthalate CAS 880141-20-8 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 Mono(2- (2- carboxyethyl) - 3- hydroxybutyl) Phthalate.

Mono(2- (2- carboxyethyl) - 3- hydroxybutyl) Phthalate (CAS 880141-20-8), molecular formula C15H18O7 and molecular weight 310.30 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Mono(2- (2- carboxyethyl) - 3- hydroxybutyl) Phthalate (C15H18O7) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
