Full Description

Neopentyl glycol (CAS 126-30-7) is a branched diol used to build durable polyester and alkyd coating resins. Industry references record it as the main glycol in powder polyester formulations and in solvent-borne polyester paints for coil, can, automotive, and general industrial coatings, and as a feedstock for plasticizers and synthetic lubricants. Supplied as a bulk polyol intermediate.

Frequently Asked Questions

What is neopentyl glycol used for?

Neopentyl glycol (NPG, CAS 126-30-7) is a branched diol used to build durable polyester and alkyd coating resins for powder, solvent-borne, coil, can, automotive, and general industrial coatings. It is also a feedstock for plasticizer esters and synthetic ester lubricants. RawSource supplies it as a bulk polyol intermediate.

What is the chemical name for neopentyl glycol?

The systematic name is 2,2-dimethylpropane-1,3-diol, CAS 126-30-7, formula C5H12O2. It is commonly abbreviated NPG.

Is neopentyl glycol supplied as a solid or liquid?

NPG is a solid diol at ambient conditions and is supplied as bulk material (e.g., flake or molten/solution depending on grade and logistics). Specify your required form and packaging when requesting a quote so the appropriate grade and handling are matched.

What are the HS code and UN number for neopentyl glycol?

NPG classifies under HS 2905.39 (diols, other) and ships under UN 2811 (2,2-dimethylpropane-1,3-diol). Confirm packing group and transport requirements against the SDS and your carrier; RawSource provides shipping documentation with each bulk order.

What is the cost of bulk neopentyl glycol?

Bulk pricing depends on grade, form, packaging, and order volume. Request a current quote from RawSource with your target quantity for landed pricing, CoA, and SDS.
