Tables with Bootstrap

To create the proposed layout, here's the example below:

<div class="container">
  <div class="row">
    <div class="col-md-6">CNPJ</div>
    <div class="col-md-6">Razão Social</div>
  </div>
    <div class="row">
        <div class="col-md-6">123456789</div>
        <div class="col-md-6">Teste</div>
    </div>
    <div class="row">
        <div class="col-md-6">123456789</div>
        <div class="col-md-6">Teste</div>
    </div>
</div>

See the example on link

But for your case, I think it's better to work with a table within a grid. So you can have the table with the two columns, and leave the space for other information, as you commented:

<div class="container">
    <div class="row">
        <div class="col-md-6">
            <table class="table">
                <tbody><tr>
                    <th>CNPJ</th>
                    <th>Razão Social</th>
                </tr>
                <tr>
                    <td>123456789</td>
                    <td>Teste</td>
                </tr>
                <tr>
                    <td>123456789</td>
                    <td>Teste</td>
                </tr>
                <tr>
                    <td>123456789</td>
                    <td>Teste</td>
                </tr>
                <tr>
                    <td>123456789</td>
                    <td>Teste</td>
                </tr>
                <tr>
                    <td>123456789</td>
                    <td>Teste</td>
                </tr>
            </tbody></table>
        </div>
        <div class="col-md-6">Outras informações</div>
    </div>
</div>
