Description

(2r-trans)-3-((6-deoxy-|A-l-mannopyranosyl)oxy)-2-(3,4-dihydroxyphenyl)-2,3-dihydro-5,7-dihydroxy-4h-1-benzopyran-4-one 3066-75-9 KST-1A3643 (CAS 3066-75-9) is a high-purity analytical reference standard with the molecular formula C7H15O4P and a molecular weight of 194.17 g/mol.

The molecular framework of (2r-trans)-3-((6-deoxy-|A-l-mannopyranosyl)oxy)-2-(3,4-dihydroxyphenyl)-2,3-dihydro-5,7-dihydroxy-4h-1-benzopyran-4-one 3066-75-9 KST-1A3643 (C7H15O4P) is characterized by a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

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.

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.
