Does 2-Hydroxypentanal CAS 87503-46-6 specify one enantiomer?

No. The hydroxyl-bearing carbon is stereogenic, but the product name and CAS number do not define an enantiomeric composition. If stereochemistry affects the process, specify the required optical form or enantiomeric ratio, chiral test method and acceptance limit rather than relying on total assay alone.

What should be defined when requesting 2-Hydroxypentanal?

State whether neat material, a solution or a stabilized form is required, then define identity, assay basis, water, acidity, related aldehydes, oligomeric or degradation limits and residual solvents. Quantity, concentration where applicable, packaging, storage conditions and the analytical evidence required for release should also be included.

2-Hydroxypentanal CAS 87503-46-6

2-Hydroxypentanal , CAS 87503-46-6 , is an alpha-hydroxy aldehyde with molecular formula C5H10O2 and molecular weight 102.13 g/mol. The C2 carbon is stereogenic, while the aldehyde and alcohol functions can support hydration, oxidation, condensation or oligomerization. Buyers should confirm whether the offered material is neat, stabilized, in solution or another characterized form and should define identity, assay basis, water, acidity and degradation limits.

Identity and physicochemical profile

Item	Technical guidance
Product identity	2-Hydroxypentanal; 2-hydroxyvaleraldehyde
CAS number	87503-46-6
Formula / molecular weight	C₅H₁₀O₂ / 102.13 g/mol
Stereochemical boundary	C2 is stereogenic; configuration is unspecified unless separately tested
Key purchase controls	Delivered form, identity, assay basis, water, acidity, hydrate or oligomer content, oxidation products, residual precursors and stabilizer

Applications and grade selection

2-Hydroxypentanal may be evaluated in controlled carbonyl, reduction, oxidation, condensation and heterocycle research. The delivered form and degradation profile can change reaction behavior, so unsupported flavor or bulk-industrial claims should not replace application testing.

Confirm whether neat, stabilized or solution material is offered and state all components.
Agree methods for assay, water, acidity, oligomers, oxidation products and stabilizer.
Test the material promptly in a minimal representative reaction before ordering project quantities.

Storage and handling

Follow the temperature, light, atmosphere and retest conditions stated for the exact grade. Minimize opening, prevent contamination and monitor assay, color and degradation during the intended storage period.

Safety, documentation and procurement

Handle as a reactive aldehyde using suitable ventilation, personal protection and a reviewed procedure. Procurement should define form, specification, sample size, package, destination, shipment conditions and documents.
