Does 2,4-Dimethylpentanoic Acid CAS 5868-33-7 specify one enantiomer?

No. Carbon 2 is stereogenic, but the product name and CAS reference do not by themselves define an enantiomeric composition. If the downstream process is stereochemistry-sensitive, specify the required optical form or enantiomeric ratio, chiral analytical method and acceptance criterion rather than relying only on total assay.

What should be fixed in a purchase specification for 2,4-Dimethylpentanoic Acid?

Define identity, GC assay or acid-value basis, water, relevant positional or process impurities, residual solvents, color or appearance and physical form. Where stereochemistry matters, add the required optical test separately. Packaging compatibility, sample method and performance in the intended synthesis should be agreed for scale-up or repeat supply.

2,4-Dimethylpentanoic Acid CAS 5868-33-7

2,4-Dimethylpentanoic Acid, also called 2,4-dimethylvaleric acid, CAS 5868-33-7, ECHA List no. 837-362-1, is a branched carboxylic acid with molecular formula C₇H₁₄O₂ and molecular weight 130.18 g/mol. The previously displayed CAS 6683-84-7 did not match this product identity and has been removed. The compound contains a stereogenic center at C2, so assay, constitutional isomers, enantiomeric requirements, acid value, water and route-derived impurities should be specified for synthesis procurement.

CAS: 5868-33-7
Synonyms: 2,4-Dimethylpentanoic Acid, 2,4-Dimethylvaleric Acid, Pentanoic acid 2,4-dimethyl-
Molecular Formula: C₇H₁₄O₂
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 physicochemical profile

Item	Technical guidance
Correct identity	2,4-Dimethylpentanoic acid; 2,4-dimethylvaleric acid
CAS / ECHA List no.	5868-33-7 / 837-362-1
Formula / molecular weight	C₇H₁₄O₂ / 130.18 g/mol
Corrected conflict	CAS 6683-84-7 does not match the 2,4-dimethylpentanoic acid structure
Key purchase controls	Identity, chromatographic assay, acid value, water, constitutional isomers, enantiomeric composition when required and residual solvents

Applications and grade selection

2,4-Dimethylpentanoic Acid may be evaluated as a branched carboxylic-acid intermediate in esterification, amidation, salt formation and carbon-chain elaboration. Reaction performance depends on water, acid value, isomer profile and downstream stereochemical requirements, so the actual lot should be tested in the buyer’s route.

Confirm CAS 5868-33-7 and distinguish the product from other dimethylpentanoic-acid positional isomers.
Define assay, acid value, water, isomer limits and any enantiomeric requirement using agreed methods.
Compare conversion, selectivity, work-up and final-product impurity carryover before project-volume purchasing.

Storage and handling

Keep the material tightly closed in compatible packaging and protect it from moisture, excessive heat and incompatible bases or oxidizers under the conditions stated in the current SDS and COA.

Safety, documentation and procurement

Handle as an organic acid using suitable gloves, eye protection and ventilation according to the current SDS. Procurement should state the intended reaction, specification, sample or project quantity, package, destination and documents.
