2-Propylheptanol (2PH, 2-PH) Supplier & Distributor

CAS Number: 10042-59-8

2-Propylheptanol, commonly referred to as 2PH or 2-PH, is a C10 branched-chain OXO alcohol used as a key raw material and chemical intermediate across a range of industrial applications. It is valued for its favorable processing characteristics, low volatility, and versatility as a building block for plasticizers and surfactants.

Description

2-Propylheptanol (2PH) is produced via the hydroformylation of propylene followed by aldol condensation and hydrogenation, yielding a branched C10 alcohol with a favorable balance of hydrophilicity and hydrophobicity. It is a colorless to pale yellow liquid with low water solubility and moderate viscosity, making it well-suited for use in both plasticizer synthesis and the production of surface-active substances.

As a plasticizer intermediate, 2PH reacts with phthalic anhydride and other acid anhydrides to form diisodecyl-type plasticizers used in PVC and other polymer systems. In surfactant applications, it serves as a hydrophobic building block for ethoxylates and other non-ionic surfactants used across cleaning, agricultural, and industrial formulations.

The Chemical Company supplies 2-Propylheptanol to manufacturers and formulators requiring reliable sourcing, consistent quality, and scalable logistics support across North American and global markets.

Frequently Asked Questions

What is 2-Propylheptanol (2PH) used for?

2-Propylheptanol is primarily used as a raw material in the production of plasticizers, particularly for PVC applications, and as a building block for surface-active substances such as non-ionic surfactants and ethoxylates. It is also used in lubricant additives, specialty esters, and coatings intermediates.

What is the CAS number for 2-Propylheptanol?

The CAS number for 2-Propylheptanol is 10042-59-8.

What industries use 2-Propylheptanol?

2PH is used across plastics and PVC manufacturing, coatings and adhesives, surfactant and cleaning product formulation, lubricants, agricultural chemicals, and specialty chemical manufacturing.

What is the molecular formula for 2-Propylheptanol?

The molecular formula for 2-Propylheptanol is C₁₀H₂₂O. It is a branched C10 alcohol produced via OXO synthesis.

What is the difference between 2-Propylheptanol and isodecanol?

2-Propylheptanol and isodecanol are both C10 branched alcohols, and 2PH is sometimes referenced as a form of isodecanol. However, isodecanol can refer to a range of branched C10 alcohol isomers, while 2-Propylheptanol refers specifically to the 2-propyl-1-heptanol isomer produced through OXO synthesis from propylene.

What plasticizers are made from 2-Propylheptanol?

2PH is used to produce plasticizers including diisodecyl phthalate (DIDP) and non-phthalate alternatives such as diisodecyl cyclohexane dicarboxylate. These plasticizers are widely used in PVC formulations for flexible films, cables, flooring, and other applications.
