D-(-)-Pantolactone CAS 599-04-2 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 130.14 g/mol gives D-(-)-Pantolactone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

D-(-)-Pantolactone (CAS 599-04-2) is a high-purity analytical reference standard with the molecular formula C6H10O3 and a molecular weight of 130.14 g/mol.

D-(-)-Pantolactone (C6H10O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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 D-(-)-Pantolactone 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.
