2,2,4-Trimethyl-1,3-pentanediol

2,2,4-Trimethyl-1,3-pentanediol (CAS 144-19-4) is a branched-chain diol supplied under trade names including TMPD Glycol and Nexcoat 795, and abbreviated commercially as TMPD (alcohol). It carries no assigned E-code and is classified under HS code 2905.39.9000.

In coatings and resin systems, TMPD acts as a reactive intermediate and plasticizer, where its branched structure reduces crystallinity and improves film flexibility without excessive softening. It also functions as a coalescent solvent in latex formulations and serves as a polyol building block in polyester and polyurethane synthesis for adhesives and sealants.

This material is available at 96% purity as a white solid, supplied in compliance with REACH registration requirements for the European market. Standard packaging formats follow industrial bulk conventions; buyers should confirm lot-specific documentation and SDS availability with the supplier prior to order.
