Which specifications matter for 5-Methyl-3-hexanol?

Specify GC assay, positional isomers, water, acid value, color and residual ketone or hydrocarbon precursors. A separate chiral method is needed only when the route requires defined stereochemistry.

Can 5-Methyl-3-hexanol be sampled for synthesis qualification?

Yes, subject to batch availability. Compare conversion, selectivity, work-up and final-product impurities in the intended esterification, oxidation or substitution before approving a larger order.

Does 5-Methyl-3-hexanol require a stereochemical specification?

The carbon bearing the hydroxyl group is stereogenic, while the general product name does not define one configuration. If downstream selectivity matters, specify racemic or enantiopure material, the required enantiomeric excess and a suitable chiral method.

5-Methyl-3-hexanol CAS 623-55-2

5-Methyl-3-hexanol , CAS 623-55-2 , is a branched secondary alcohol with molecular formula C7H16O and molecular weight 116.20 g/mol. The hydroxyl-bearing C3 carbon is stereogenic, so a standard commercial grade may be racemic unless a stereochemical specification states otherwise. Buyers should define identity, GC assay, constitutional isomers, water, acid value and residual precursors, then qualify esterification, oxidation or substitution performance in the intended route.

CAS: 623-55-2
Synonyms: 5-Methyl-3-hexanol, 5-Methylhexan-3-ol, 3-Hexanol 5-methyl-, 3-Hydroxy-5-methylhexane
Molecular Formula: C₇H₁₆O
Grade: Confirm identity, assay method, water or residual solvents, product-specific impurities and physical form against the current COA; no end-use grade is assumed.
Package: State required quantity and destination; confirm the current container, light or moisture protection, net weight, storage conditions and transport requirements against the current COA and SDS.

Applications and grade selection

5-Methyl-3-hexanol may be evaluated in esterification, oxidation, substitution and other controlled synthesis routes. Process value depends on isomer profile, water, acidity and downstream stereochemical needs, so broad fragrance, solvent or intermediate claims should be supported by application testing.

Define whether racemic material is acceptable or a stereochemically controlled grade is required.
Set limits for GC assay, positional isomers, residual precursors, water and acid value.
Compare conversion, selectivity, work-up and final-product impurity carryover at small scale.

Storage and handling

Keep tightly closed in compatible packaging away from heat, ignition sources, oxidizers and moisture under the current SDS and COA. Record sampling and storage history during qualification.

Safety, documentation and procurement

Handle as a combustible organic liquid using suitable ventilation, gloves and eye protection. Procurement should state the reaction, specification, stereochemical needs, quantity, packaging, destination and documents.
