Is n-Butanol the same as isobutanol, sec-butanol or tert-butanol?

No. n-Butanol is butan-1-ol with CAS 71-36-3. Isobutanol, 2-butanol and tert-butanol are different structural isomers, so an industrial order must use the exact name and CAS rather than “butanol” alone.

Which quality controls matter for an industrial n-Butanol solvent grade?

Confirm assay, water, acidity, colour and nonvolatile residue, together with the associated test methods. Process-specific limits for other alcohol isomers or carbonyl impurities may also be required where solvent behaviour, colour or reaction consistency is critical.

Can n-Butanol be substituted directly by another butanol isomer in ester production?

Not automatically. The alcohol structure affects the ester identity and can change reaction, separation and final-product properties. For butyl esters, define the intended alcohol isomer and verify the reaction specification instead of assuming an equal-weight solvent substitution.

n-Butanol (1-Butanol) CAS 71-36-3

n-Butanol (1-Butanol, CAS 71-36-3, EC 200-751-6) is the straight-chain primary C4 alcohol used as an industrial solvent and a feedstock for butyl esters such as n-Butyl Acetate and other chemical synthesis. It is distinct from 2-butanol, isobutanol and tert-butanol. Confirm assay, water, acidity, color, nonvolatile residue where relevant, packaging and transport classification against the current TDS, COA and SDS. The liquid and vapor are flammable, so receiving, storage and transfer controls should be reviewed before shipment.

Product Overview

n-Butanol (1-butanol, CAS 71-36-3, EC 200-751-6) is the straight-chain primary C4 alcohol used as an industrial solvent and as a feedstock for butyl esters, coatings, inks and chemical synthesis. It is distinct from 2-butanol, isobutanol and tert-butanol. Confirm assay, water, acidity, color, relevant impurities and packaging for the offered grade. The liquid and vapor are flammable and can cause serious eye damage and other acute effects; use ventilation, ignition control and the current SDS.
