IDENTIFICATION: 1-Methoxy-2-hydroxypropane or propylene glycol methyl ether (PGME) is a clear colorless liquid. It has a sweet odor and a bitter taste. It mixes easily in water. USE: PGME is an important commercial chemical. It is used in paint and finish removers. It is a solvent for cellulose, acrylics, dyes, inks and stains. It is also used in antifreeze and coolant for diesel engines.
Propylene glycol methyl ether (PGME) exhibits excellent solvent and coupling properties. A toxicity database provided evidence suggesting that PGME might be a useful substitute for xylene in histotechnology and histochemistry applications. Tissue specimens were fixed, cleared in either PGME or xylene, embedded in paraffin wax, then dewaxed in either PGME or xylene. Sections were treated with the following stains: hematoxylin & eosin (H & E), three special stains of the Gordon/Sweet silver staining method, PAS, and Masson's trichrome, and immunostains including actin, CD3, CD34, CK, CK7/CK9, Ki-67, and ER/PR. The sections were mounted in a resinous medium consisting of PGME and pinene copolymer, then examined under a microscope. Variables such as water tolerance, dimension change, organic solvency, and anti-fading efficacy also were assessed.
Depending on the application, PGME performance was equal to or exceeded that of xylene. PGME provided better optical clarity and nuclear detail, did not harden the tissue samples, conserved tissue antigenicity, and was amenable to resinous mounting. Tissues not dehydrated with absolute ethanol also were processed properly. Tissues treated with PGME did not warp or contract compared to those treated with xylene (p < 0.0001). PGME, however, exhibited less organic solvency than xylene. There was no discernible change in the colors of stains in sections processed with PGME even after storage for two years. These results suggest that PGME is a novel xylene substitute for applications in histotechnology and histochemistry.

General Description
A colorless liquid. Flash point near 89°F. Less dense than water. Contact irritates skin, eyes and mucous membranes. Prolonged exposure to vapors may cause coughing, shortness of breath, dizziness and intoxication. Vapors heavier than air. Used as a solvent and as an antifreeze agent.
Air & Water Reactions
Highly flammable. Soluble in water. Oxidizes readily in air to form unstable peroxides that may explode spontaneously
