Structure of Sodium pent-4-ynoate, CAS 101917-30-0 — Structure · C5H5NaO2

CAS number: 101917-30-0
Molecular formula: C₅H₅NaO₂
Molecular weight: 120.08 g/mol
Standard packing: 1kg / 25kg / 100kg

CAS 101917-30-0, Sodium pent-4-ynoate, is a C5H5NaO2 ester – the protected form of the corresponding acid.

The ester is the protected form of the acid: it survives steps the free acid would not, and is cleaved when the acid is wanted. The salt form is chosen for handling and storage; the free base or free acid is generated in situ when the reaction needs it.

The formula C5H5NaO2 resolves to 5 carbons with 2 oxygens and one sodium counter-ion. 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

Esters hydrolyse slowly in the presence of moisture, so the lot is stored dry and away from bases.

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.
