Does CAS 600-11-3 guarantee a single stereoisomer of 2,3-Dichloropentane?

No. 2,3-Dichloropentane has stereoisomers, and a commercial material may be an isomeric mixture unless a stereochemical composition is specified. Where isomer composition matters, confirm the analytical method, assay basis and isomeric profile rather than relying on the CAS number or total purity alone.

What should a purchase specification include when 2,3-Dichloropentane is used as a synthesis intermediate?

Set total assay, the agreed GC method, individual stereoisomer or isomer limits where relevant, water, related chlorinated compounds, residual starting materials, appearance and packaging. Qualification should also compare conversion and impurity carryover in the actual route, because total purity alone may not predict downstream selectivity.

2,3-Dichloropentane CAS 600-11-3

2,3-Dichloropentane , CAS 600-11-3 and EC 209-983-2 , is a vicinal dichloroalkane with molecular formula C5H10Cl2 and molecular weight 141.04 g/mol. The structure contains two stereogenic centers, so an unspecified commercial product may contain more than one stereoisomer. It is supplied for controlled research or synthesis projects, with identity, assay, stereoisomer profile, other impurities, physical form and packaging defined by the offered specification rather than a universal 99% claim.

CAS: 600-11-3
Synonyms: 2,3-Dichloropentane, Pentane, 2,3-dichloro-, 2,3-Dichloropentane stereoisomer mixture
Einecs: 209-983-2
Molecular Formula: C₅H₁₀Cl₂
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 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	2,3-Dichloropentane
CAS / EC	600-11-3 / 209-983-2
Formula / molecular weight	C₅H₁₀Cl₂ / 141.04 g/mol
Stereochemical consideration	The structure has two stereogenic centers; confirm whether the offer is unspecified material, a mixture or a defined stereoisomer
Commercial status	Research or synthesis intermediate with supplier-specific assay and impurity limits
Key controls	Identity, chromatographic assay, stereoisomer profile, other impurities, water and physical form

Applications and grade selection

2,3-Dichloropentane is evaluated as a halogenated C5 building block in controlled substitution, elimination and related process-development work. Generic claims for pharmaceutical, pesticide or solvent use should not replace route-specific testing and regulatory review.

State whether the project requires total assay only or a defined stereoisomer composition.
Compare reaction conversion, selectivity, impurity carryover and final-product quality with the approved source.
Confirm flammable-liquid classification, compatible packaging and destination-specific transport conditions before shipment.

Storage and handling

Keep the original container tightly closed in a cool, dry, ventilated area away from heat, ignition sources and incompatible oxidizers. Follow the current SDS for transfer, grounding, spill response and storage segregation.

Safety, documentation and procurement

Use suitable gloves, eye protection and ventilation according to the current SDS and site assessment. Procurement should specify assay, stereoisomer requirements, quantity, package, destination, shipping terms and required technical documents.
