((3AS,5R,6S,6aS)-6-hydroxy-2,2-dimethyltetrahydrofuro[2,3-d][1,3]dioxol-5-yl)(morpholino)methanone

China [CN]

1. Appearance: White to off-white crystalline powder (typical form of a chiral heterocyclic amide intermediate; higher purity results in better crystallinity); 2. Solubility: Excellent water solubility (the morpholine ring is a strongly hydrophilic group), readily soluble in methanol, ethanol, and water, soluble in dichloromethane and tetrahydrofuran, sparingly soluble in petroleum ether/ethyl acetate (significantly higher hydrophilicity than ordinary aryl intermediates); 3. Stability: Stable under sealed, dry storage at room temperature; avoid strong acids (dioxolane ring opening), strong reducing agents (amide bond reduction), and high temperatures (≥100℃ can lead to dehydroxylation); 4. Melting point: Expected 160~180℃ (multiple chiral centers + heterocycle + amide group, resulting in a relatively high melting point).
