Chemical Structure

1,2-Benzenedicarboxylic acid, heptyl undecyl ester, branched and linear CAS 111381-90-9 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 1,2-Benzenedicarboxylic acid, heptyl undecyl ester, branched and linear.

1,2-Benzenedicarboxylic acid, heptyl undecyl ester, branched and linear (CAS 111381-90-9) is a high-purity analytical reference standard with the molecular formula C26H42O4 and a molecular weight of 418.61 g/mol.

1,2-Benzenedicarboxylic acid, heptyl undecyl ester, branched and linear (C26H42O4) contains a steroid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

CATO manufactures 1,2-Benzenedicarboxylic acid, heptyl undecyl ester, branched and linear 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.
