Chemical Structure

beta-Propiolactone CAS 57-57-8 chemical structure

Description

The occurrence of beta-Propiolactone is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

beta-Propiolactone (CAS 57-57-8) is a high-purity analytical reference standard with the molecular formula C3H4O2 and a molecular weight of 72.06 g/mol.

beta-Propiolactone (C3H4O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures beta-Propiolactone 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.
