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), also called Pentane, 2,3-dichloro-, is a vicinal dichloroalkane with two stereogenic centers. It serves as a halogenated C5 building block for substitution and elimination reactions under controlled conditions. Identity, assay, stereoisomer profile, other impurities, water content and physical form are key specification points. COA, TDS and SDS are available for specification review and handling guidance.

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.

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.
