Chloro 2,3,4,6-Tetra-O-acetyl-α-D-mannopyranoside CAS 14257-40-0

Description

The occurrence of Chloro 2,3,4,6-Tetra-O-acetyl-α-D-mannopyranoside is closely related to a carbohydrate-derived structure, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Chloro 2,3,4,6-Tetra-O-acetyl-α-D-mannopyranoside (CAS 14257-40-0), a certified reference material (molecular formula C6H11ClO5, MW 198.60 g/mol) for analytical method development and quality control.

Owing to a carbohydrate-derived structure, chlorine substitution, Chloro 2,3,4,6-Tetra-O-acetyl-α-D-mannopyranoside is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 198.60 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
