Request SDS →Dioctyl phthalate (CAS 117-81-7) — bis(2-ethylhexyl) phthalate, commonly DOP or DEHP — is a phthalate-ester plasticizer. It is used to plasticize PVC and other polymers in products such as wire and cable, flooring, coated fabrics, and film, and as a hydraulic and dielectric fluid.
Frequently Asked Questions
What is dioctyl phthalate (DOP) used for?
DOP — bis(2-ethylhexyl) phthalate, also called DEHP — is a general-purpose phthalate-ester plasticizer for flexible PVC and other polymers. Typical applications include wire and cable insulation, flooring, coated fabrics, and film, plus use as a hydraulic and dielectric (capacitor) fluid.
What is the difference between dioctyl phthalate (DOP) and DOTP?
DOP is a phthalate ester (CAS 117-81-7, an ortho-phthalate); DOTP is the terephthalate isomer, dioctyl terephthalate (CAS 6422-86-2). Both are bis(2-ethylhexyl) C24H38O4 plasticizers but differ in ester linkage and regulatory positioning. Confirm CAS on the CoA.
What is the HS code for dioctyl phthalate?
DOP classifies under HS 2917.32 — dioctyl orthophthalates. The CAS is 117-81-7 and molecular weight is approximately 390.6 g/mol (C24H38O4). Full identity is documented on the CoA supplied with each shipment.
What is the molecular weight of dioctyl phthalate?
DOP has molecular formula C24H38O4, molecular weight approximately 390.6 g/mol, CAS 117-81-7. The SDS and CoA provided with each bulk order carry the full physical-property data set.
What is the cost of bulk dioctyl phthalate?
Bulk DOP pricing varies with volume, packaging (drums, totes, or bulk), and destination, and tracks 2-ethylhexanol and phthalic anhydride feedstock markets. We do not publish a fixed price; submit a bulk RFQ for a current quote with CoA and SDS.
