Structure of 1-Pentyn-3-ol, CAS 4187-86-4 — Structure · C5H8O

CAS number: 4187-86-4
Molecular formula: C₅H₈O
Molecular weight: 84.12 g/mol
Standard packing: 1kg / 25kg / 100kg

1-Pentyn-3-ol (CAS 4187-86-4) is a C5H8O alkyne building block supplied in kilogram lots.

Partial hydrogenation, cycloaddition and alkyne metathesis are the reactions this entry is bought for, and the substitution pattern is what makes them selective.

The formula C5H8O resolves to 5 carbons with one oxygen. Short-chain entries of this size are volatile enough that headspace and packing matter: the lot is shipped in sealed units and opened in a fume hood.

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. Where a specification has to be met on paper before shipment, it is agreed in writing and the lot is qualified against it rather than against the catalogue text.
