Which 2,4-Dimethylpentanoic Acid specifications should be agreed?

Specify GC assay, water, acid value, color and limits for positional isomers, residual alcohol or aldehyde precursors and other route-related impurities.

Does 2,4-Dimethylpentanoic Acid require a stereochemical specification?

The molecule can have stereochemical composition relevant to some routes. State any required configuration or enantiomeric excess separately; a routine CAS-matched grade may not control it.

Why should acid value and chromatographic assay both be reviewed for 2,4-Dimethylpentanoic Acid?

Acid value reflects total titratable acidity, while chromatography distinguishes the target acid from structural isomers and neutral route impurities. Use both when stoichiometry and impurity carryover matter; neither result alone establishes full equivalence.

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

2,4-Dimethylpentanoic Acid , also known as 2,4-dimethylvaleric acid , is identified by CAS 5868-33-7 and EC 837-362-1 . Its molecular formula is C7H14O2 and molecular weight is 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.

Identity and physicochemical profile

Item	Technical guidance
Correct identity	2,4-Dimethylpentanoic acid; 2,4-dimethylvaleric acid
CAS / EC	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.
