The ideal first step would be to use DBI placeholders instead of creating a string-SQL statement. The second step would be to use Text::CSV_XS for parsing your delimited input file.

my $sth_insert = $dbi->prepare(<<'SQL');
    INSERT INTO biochemical
         VALUES (?,?,?,?,?,?,?,?,?,?,...,?)
SQL

for my $row (@rows) {
    $sth_insert->execute( @$row );
};

By using DBI placeholders, you don't need to care about special characters like double quotes in strings.

Then, when inserting, switch off the RaiseError flag:

local $sth_insert->{RaiseError} = 0;
for my $row (@rows) {
    $sth_insert->execute( @$row );
};

That way, the script does not die anymore on insert errors.
