Fluorine-containing ether compound, lubricant for magnetic recording medium, and magnetic recording medium

Abstract

This fluorine-containing ether compound is represented by formula (1) shown below. R1—CH2—R2—CH2—R3  (1) In formula (1), R2 is a perfluoropolyether chain represented by a formula (2) shown below. R1 is a terminal group that is bonded to R2 via a CH2 group, and is represented by a formula (3) shown below. R3 is bonded to R2 via a CH2 group, is a terminal group having at least one hydroxyl group, and may be the same as, or different from, R1. —(CF2)p-1—O—((CF2)pO)q—(CF2)p-1—  (2) In formula (2), p represents an integer of 2 to 3, and q indicates the average polymerization degree and is a number within a range from 1 to 20. —O(CH2—CH(OH)—CH2—O)2—CH2—(CH2)n—OH  (3) In formula (3), n represents an integer of 1 to 8.
