Structure of Carbamic acid, N-3-butyn-1-yl-, 9H-fluoren-9-ylmethyl ester, CAS 1942058-91-4 — Structure · C19H17NO2

CAS number: 1942058-91-4
Molecular formula: C₁₉H₁₇NO₂
Molecular weight: 291.3 g/mol
Standard packing: 1kg / 25kg / 100kg

Carbamic acid, N-3-butyn-1-yl-, 9H-fluoren-9-ylmethyl ester is an alkyne entry under CAS 1942058-91-4: C19H17NO2, 291.3 g/mol, standard packing 1kg / 25kg / 100kg.

Because the alkyne hydrogen is acidic enough to deprotonate cleanly, this entry is usually the nucleophile in whichever step it appears in.

The formula C19H17NO2 resolves to 19 carbons with 2 oxygens and one nitrogen. Long-chain entries of 19 carbons behave as oils or waxy solids and are warmed before packing so that the unit weight is accurate.

Handling and storage

Alkynes are held closed, dry and out of direct light; the silylated entries are also moisture sensitive and are packed under inert gas.

Ordering

The unit weights held are 1kg / 25kg / 100kg. A split shipment across two of those sizes is treated as one lot and one certificate. Identity is confirmed by NMR and MS at release, and the assay value belongs to the lot rather than to the catalogue entry.
