(2R,3S)-2,3,4-Trihydroxy-butyrolactone 2,3-Cyclohexyl Ketal CAS 186803-48-5 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 (2R,3S)-2,3,4-Trihydroxy-butyrolactone 2,3-Cyclohexyl Ketal.

(2R,3S)-2,3,4-Trihydroxy-butyrolactone 2,3-Cyclohexyl Ketal (CAS 186803-48-5) is a high-purity analytical reference standard with the molecular formula C10H14O5 and a molecular weight of 214.22 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, (2R,3S)-2,3,4-Trihydroxy-butyrolactone 2,3-Cyclohexyl Ketal is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 214.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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 (2R,3S)-2,3,4-Trihydroxy-butyrolactone 2,3-Cyclohexyl Ketal 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.
