Chemical Structure

Ethyl Citrate CAS 4552-00-5 chemical structure

Description

CATO manufactures Ethyl Citrate 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.

Ethyl Citrate (CAS 4552-00-5), molecular formula C8H12O7 and molecular weight 220.18 g/mol, is a CATO reference standard with documented purity and traceability.

Ethyl Citrate (C8H12O7) contains a carbohydrate-derived structure. It is notably hygroscopic, 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.
