Structure of 4-Hexynoic acid, CAS 41143-12-8 — Structure · C6H8O2

CAS number: 41143-12-8
Molecular formula: C₆H₈O₂
Molecular weight: 112.13 g/mol
Standard packing: 1kg / 25kg / 100kg

4-Hexynoic acid (CAS 41143-12-8) is a C6H8O2 alkyne building block supplied in kilogram lots.

Both alkyne carbons carry substituents, so the triple bond is carried through a route rather than functionalised at a terminal C-H.

The formula C6H8O2 resolves to 6 carbons with 2 oxygens. 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

Supplied in 1kg / 25kg / 100kg; a gram-scale sample is quoted against the same specification, so the analysis seen at sample stage is the analysis of the kilo lot.
