| Abstract | The category contains four structurally related propylene glycol ethers: - Propylene Glycol n-Butyl Ether (PnB, 5131-66-8, major (“alpha”) isomer, 29387-86-8 isomeric mixture) - Dipropylene Glycol n-Butyl Ether (DPnB, 29911-28-2 major isomer or 35884-42-5 isomeric mixture)) - Dipropylene Glycol Methyl Ether Acetate (DPMA, 88917-22-0 isomeric mixture) - Tripropylene Glycol Methyl Ether (TPM, 20324-33-8 one of the isomers and 25498-49-1 isomeric mixture) The alpha (secondary alcohol) form is kinetically favored during synthesis. PnB is available as the isomeric mixture in which the alpha isomer is the predominant isomer (ca. 95%. DPnB, DPMA and TPM are commercially produced as mixtures of isomeric components in which the internal ether linkages may be adjacent to either primary or secondary carbon atoms. Thus, for DPMA and DPnB the commercially produced products may contain up to 4 such isomers. In the case of TPM, the commercially produced product may contain up to 8 such isomers. Data for these propylene glycol ethers are supplemented with data from three propylene glycol ethers that are closely related to the category members in molecular structure, physicochemical properties and toxicity and thus extend the category. These compounds are: - Propylene Glycol Methyl Ether (PM; CAS No. 107-98-2) - Propylene Glycol Methyl Ether Acetate (PMA; CAS No. 108-65-6) - Dipropylene Glycol Methyl Ether (DPM; CAS No. 34590-94-8 isomeric mixture and 20324-32-7 major isomer) PM and PMA were reviewed at SIAM 11 and DPM was reviewed at SIAM 12. All were assigned as low priority for further work. |
