Does CAS 15146-94-8 specify the stereochemistry of 5-Chloro-2-pentanol?

No. 5-Chloro-2-pentanol has a stereogenic carbon at position 2, but the CAS number alone does not state racemic or enantiomerically enriched composition. Specify the required stereochemical form, optical or chiral method and acceptance limit when this affects the downstream route.

Which batch controls should be set for 5-Chloro-2-pentanol?

Set limits for GC assay, positional chloropentanol isomers, chlorinated by-products, unreacted precursors, water, residual solvents, color and, where required, enantiomeric composition. Include the intended process, quantity, package and required analytical documents in the inquiry so the offered lot can be assessed consistently.

5-Chloro-2-pentanol CAS 15146-94-8

5-Chloro-2-pentanol, also called 5-chloropentan-2-ol, CAS 15146-94-8, ECHA list no. 825-413-0, is 5-chloropentan-2-ol with formula C₅H₁₁ClO and molecular weight 122.59 g/mol. The molecule has a stereogenic center at carbon 2, but the CAS number alone does not specify enantiomeric composition. Buyers should state racemic, enriched or single-enantiomer requirements and control GC assay, positional isomers, chlorinated by-products, water and residual solvents.

CAS: 15146-94-8
Synonyms: 5-Chloro-2-pentanol, 5-Chloropentan-2-ol, 2-Pentanol 5-chloro-
Molecular Formula: C₅H₁₁ClO
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.

Identity and specification

Item	Verified purchasing information
Product	5-Chloro-2-pentanol; 5-chloropentan-2-ol
CAS / ECHA list no.	15146-94-8 / 825-413-0
Formula / molecular weight	C5H11ClO / 122.59 g/mol
Critical selection point	Racemic or specified enantiomeric composition

5-Chloro-2-pentanol contains both a secondary alcohol and a terminal chloride. Positional identity and stereochemical form should be confirmed because related chloropentanols and enantiomers can have different synthesis performance.

Quality controls for purchasing

Define racemic, enantiomerically enriched or single-enantiomer material and the chiral test method when required.
Set GC limits for positional isomers, chlorinated by-products, unreacted precursors and unknown impurities.
Specify water, residual solvents, color and assay basis for moisture- or selectivity-sensitive reactions.

Applications and grade selection

The chloroalcohol may be evaluated as a bifunctional fine-chemical intermediate. Suitability depends on whether the process uses the alcohol, chloride or stereocenter selectively. A sample should be tested for conversion, selectivity and impurity carryover in the intended route.

Storage and handling

Keep tightly sealed in a compatible container and protect from heat, oxidizers, strong acids and strong bases. Use the temperature and headspace conditions documented by the supplier rather than assuming refrigeration or inert gas is always required.

Documentation and quotation details

State stereochemical form, assay, isomer and water limits, residual-solvent requirements, quantity, packaging, destination and schedule. Request COA, SDS, chiral data when applicable and a sample for route qualification.
