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

A fluorine-containing ether compound that is represented by a following formula (1):

• (in the formula (1), R1 is represented by a formula (2-1) or a formula (2-2);
• R2 is a perfluoropolyether chain;
• R4 is an organic group having at least one polar group and having 1 to 50 carbon atoms;
• R3 is a divalent linking group having at least one hydroxyl group;
• n is an integer of 0 to 2;
• in a case where n is 1 or 2, a part or all of a plurality of R2's may be identical to each other or may be different from each other;
• and in a case where n is 2, two R3's may be identical to each other or may be different from each other)
• (in the formula (2-1), X1 is a divalent linking group including no polar groups, optionally including an ether oxygen atom, and having 1 to 12 carbon atoms;
• Y1 and Z1 are each independently an organic group or a hydrogen atom, the organic group having 1 to 30 carbon atoms and optionally including at least one of a polar group and an ether oxygen atom;
• and Y1 and Z1 may bond to each other to form a ring)
• (in the formula (2-2), X2 is a divalent linking group including no polar groups, optionally including an ether oxygen atom, and having 1 to 12 carbon atoms;
• Y2 is an organic group or a hydrogen atom, the organic group having 1 to 30 carbon atoms and optionally including at least one of a polar group and an ether oxygen atom;
• Z2 is an organic group optionally including at least one of a polar group and an ether oxygen atom and having 1 to 30 carbon atoms;
• and Y2 and Z2 may bond to each other to form a ring).
