Description

Bis(1-methylheptyl) phthalate (CAS 131-15-7), also known as dioctan-2-yl benzene-1,2-dicarboxylate, is a high-purity phthalate ester with the molecular formula C24H38O4. This specialized chemical is widely utilized as a plasticizer in polymer formulations, offering excellent compatibility with PVC, nitrocellulose, and synthetic rubbers. Its branched alkyl structure provides enhanced low-temperature flexibility and resistance to extraction compared to linear phthalates. The compound appears as a clear, colorless to pale yellow viscous liquid with minimal volatility (typical vapor pressure <0.01 mmHg at 20??C). Our product is rigorously tested to meet ??98% purity standards by GC analysis, with acid value <0.1 mg KOH/g and moisture content <0.1%. Suitable for research applications requiring precise plasticizer performance studies, this material is packaged under nitrogen atmosphere to ensure stability and shipped with comprehensive analytical documentation including GC chromatograms and NMR spectra.

Application

Bis(1-methylheptyl) phthalate serves as a high-performance plasticizer for flexible PVC products requiring superior low-temperature properties, such as automotive interiors and cold-weather cables. In materials science research, it’s employed to study the effects of branched-chain plasticizers on polymer crystallization kinetics and glass transition temperatures. The compound also finds use as a dielectric fluid in capacitor development due to its stable dielectric constant (?ลก?5-6 at 1kHz) and high volume resistivity (>1012 ????cm).
