Does 2-Chloropropanal CAS 683-50-1 specify one enantiomer?

No. The carbon bearing chlorine is stereogenic, but the product name and CAS number do not define an enantiomeric composition. If the process is stereosensitive, state the required optical form or enantiomeric ratio, chiral analytical method and acceptance limit instead of relying only on total assay.

What commercial form and quality controls should be defined for 2-Chloropropanal?

Confirm whether the offered material is neat, in solution or stabilized, and identify any solvent or stabilizer. The purchase specification should define structural identity, assay basis, water, acidity, related aldehydes, oligomeric or degradation limits and residual precursors, together with packaging, storage conditions and release data.

2-Chloropropanal CAS 683-50-1

2-Chloropropanal, also called α-chloropropionaldehyde or 2-chloropropionaldehyde, CAS 683-50-1, is an alpha-chloro aldehyde with molecular formula C₃H₅ClO and molecular weight 92.52 g/mol. It contains a stereogenic C2 center and a reactive aldehyde, making commercial form, stereochemical status, water, acidity, oligomerization and degradation behavior important. Buyers should qualify the actual delivered material and storage conditions rather than rely on unsupported bulk purity or universal shelf-life claims.

CAS: 683-50-1
Synonyms: 2-Chloropropanal, α-Chloropropionaldehyde, 2-Chloropropionaldehyde, Propanal 2-chloro-
Molecular Formula: C₃H₅ClO
Grade: Confirm the supplied form or concentration, assay, reactive impurities, stabilizer or inhibitor status, storage controls and handling requirements against the current COA and SDS.
Package: State required quantity and destination; confirm the approved container or cylinder, inerting or stabilizer needs, closure or valve, fill quantity, temperature controls and dangerous-goods requirements against the SDS.

Identity and physicochemical profile

Item	Technical guidance
Product identity	2-Chloropropanal; alpha-chloropropionaldehyde
CAS number	683-50-1
Formula / molecular weight	C₃H₅ClO / 92.52 g/mol
Reactive features	One aldehyde, one alpha-chloro substituent and a stereogenic C2 center
Key purchase controls	Identity, assay basis, water, acidity, oligomers, oxidation products, residual precursors, stabilizer and physical form

Applications and grade selection

2-Chloropropanal may be evaluated in controlled carbonyl, substitution and condensation chemistry. Its aldehyde and alpha-chloro functions can create condition-dependent side reactions, so qualification should include the buyer’s actual solvent, base, temperature, hold time and work-up.

Confirm whether neat material, solution or another characterized form is offered.
Agree assay, water, acidity, oligomer, degradation and stabilizer limits using suitable methods.
Run a minimal representative reaction before approving project-volume supply.

Storage and handling

Keep sealed under the temperature, light and atmosphere conditions stated in the current documentation. Minimize opening and monitor assay, color and oligomer or degradation growth during the intended storage period.

Safety, documentation and procurement

Handle as a reactive chlorinated aldehyde with closed transfer where practicable, effective ventilation and suitable personal protection. Procurement should define form, specification, quantity, package, shipment conditions and destination.
