Application boundary
3-Methylvaleric Acid is a branched-chain C6 carboxylic acid, also called 3-Methylpentanoic Acid. It must be distinguished from 2-Methylvaleric Acid and straight-chain Hexanoic Acid; a generic isovaleric-acid label is not precise enough.

FAQ - Technical & Supply Chain
-
Q:
How should 3-Methylvaleric Acid be distinguished from other C6 carboxylic-acid isomers?
A: Use 3-Methylvaleric Acid or 3-Methylpentanoic Acid with CAS 105-43-1. It is not 2-Methylvaleric Acid, 4-Methylvaleric Acid, Hexanoic Acid or Isovaleric Acid; those isomers have different CAS numbers and physical profiles. Put the CAS number and full positional name on the order. -
Q:
What is 3-Methylvaleric Acid used for?
A: It is used as a branched C6 carboxylic-acid building block for esters, flavors, fragrances, pharmaceuticals, agrochemicals and specialty surfactants. The branched structure can modify volatility, solubility and hydrolytic stability compared with straight-chain hexanoic acid. -
Q:
Which specification and delivery details should be agreed for 3-Methylvaleric Acid?
A: Agree GC assay and isomer profile, water, color, acidity or acid value, density, refractive index and any high-boiling residue with the methods. Confirm the offered package, net quantity, compatible closure, transport classification, manufacturing date and storage conditions. -
Q:
What should be confirmed about the offered physical form?
A: Confirm whether the material is supplied as liquid, low-melting solid or another form, and check the corresponding packaging, heating or transfer requirements. 3-Methylvaleric Acid should be stored in closed, corrosion-resistant containers away from moisture and incompatible oxidizers. -
Q:
What are the typical physical properties of 3-Methylvaleric Acid?
A: 3-Methylvaleric Acid is usually a liquid at room temperature, with boiling point around 196-198 C, density about 0.93 g/mL and flash point near 85 C. Compare offered lot data against the agreed specification and confirm whether temperature control is needed for shipping.
