Description

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.

(2S,3R,4S,5S,6R)-2-[(1S,2S,3R,4S,6R)-3-[(2R,3R,6S)-6-(aminomethyl)-3-azanyl-oxan-2-yl]oxy-4,6-bis(azanyl)-2-oxidanyl-cyclohexyl]oxy-4-azanyl-6-(hydroxymethyl)oxane-3,5-diol sulfate (2S,3R,4S,5S,6R)-4-amino-2-[(1S,2S,3R,4S,6R)-4,6-diamino-3-[[(2R,3R,6S)-3-amino-6-(aminomethyl)-2-oxanyl]oxy]-2-hydroxycyclohexyl]oxy-6-(hydroxymethyl)oxane-3,5-diol sulfate 729-81-7 A837687 (CAS 729-81-7) is a high-purity analytical reference standard with the molecular formula C9H9F9 and a molecular weight of 288.15 g/mol.

Owing to fluorine substitution, (2S,3R,4S,5S,6R)-2-[(1S,2S,3R,4S,6R)-3-[(2R,3R,6S)-6-(aminomethyl)-3-azanyl-oxan-2-yl]oxy-4,6-bis(azanyl)-2-oxidanyl-cyclohexyl]oxy-4-azanyl-6-(hydroxymethyl)oxane-3,5-diol sulfate (2S,3R,4S,5S,6R)-4-amino-2-[(1S,2S,3R,4S,6R)-4,6-diamino-3-[[(2R,3R,6S)-3-amino-6-(aminomethyl)-2-oxanyl]oxy]-2-hydroxycyclohexyl]oxy-6-(hydroxymethyl)oxane-3,5-diol sulfate 729-81-7 A837687 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 288.15 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.

As a certified reference material (CRM), (2S,3R,4S,5S,6R)-2-[(1S,2S,3R,4S,6R)-3-[(2R,3R,6S)-6-(aminomethyl)-3-azanyl-oxan-2-yl]oxy-4,6-bis(azanyl)-2-oxidanyl-cyclohexyl]oxy-4-azanyl-6-(hydroxymethyl)oxane-3,5-diol sulfate (2S,3R,4S,5S,6R)-4-amino-2-[(1S,2S,3R,4S,6R)-4,6-diamino-3-[[(2R,3R,6S)-3-amino-6-(aminomethyl)-2-oxanyl]oxy]-2-hydroxycyclohexyl]oxy-6-(hydroxymethyl)oxane-3,5-diol sulfate 729-81-7 A837687 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.
