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,4S,5S)-6-chloro-2,3,4,5-tetrahydroxyhexanal.
(2R,3S,4S,5S)-6-chloro-2,3,4,5-tetrahydroxyhexanal (CAS 40656-44-8) is a high-purity analytical reference standard with the molecular formula C6H11ClO5 and a molecular weight of 198.60 g/mol.
(2R,3S,4S,5S)-6-chloro-2,3,4,5-tetrahydroxyhexanal (C6H11ClO5) contains a carbohydrate-derived structure, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), (2R,3S,4S,5S)-6-chloro-2,3,4,5-tetrahydroxyhexanal meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
