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)-5-(((2R,3R,4R,5S)-3,4-Dihydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)oxy)-2,3,4-trihydroxypentanal.
(2R,3S,4S)-5-(((2R,3R,4R,5S)-3,4-Dihydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)oxy)-2,3,4-trihydroxypentanal (CAS 78088-21-8) is a high-purity analytical reference standard with the molecular formula C10H18O9 and a molecular weight of 282.24 g/mol.
Owing to a carbohydrate-derived structure, (2R,3S,4S)-5-(((2R,3R,4R,5S)-3,4-Dihydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)oxy)-2,3,4-trihydroxypentanal is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 282.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
