Structure of 4-Pentynoic acid, CAS 6089-09-4 — Structure · C5H6O2

CAS number: 6089-09-4
Molecular formula: C₅H₆O₂
Molecular weight: 98.10 g/mol
Standard packing: 1kg / 25kg / 100kg

4-Pentynoic acid is an alkyne entry under CAS 6089-09-4: C5H6O2, 98.10 g/mol, standard packing 1kg / 25kg / 100kg.

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 C5H6O2 resolves to 5 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

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.
