More specifically, sodium nitrAte [1], with an a, NaNO₃, has a rat LD50 of over 3 g/kg, has a signal word of Warning, and has no toxicity label (it has H272 and H319, an oxidizer and causes serious eye irritation). Sodium nitrIte [2], with an i, NaNO₂, has a rat LD50 of around 85 mg/kg, almost two orders of magnitude smaller, has a signal word of Danger, and has H301/acute toxicity with a skull-and-crossbones label, in addition to H272 and H319, and H400 (very toxic to aquatic life) too. The two are very different. Somewhat distressingly, searching for sodium nitrite on Amazon comes up with some sodium nitrate results, and searching sodium nitrate comes up with at least one product that is mostly (if still only 6%) sodium nitrite. I wish search engine developers would not insist on assuming any similar word is just a typo: that's a potentially very dangerous mixup. Searching for sodium nitrite and selecting a seller of >98% on Amazon (US) did give a suicide-instruction book as a suggestion when I searched initially (logged out, private tab), but after looking up the SDSs and coming back to this, I no longer get anything of the sort. I doubt that legitimate chemical suppliers like Fisher/VWR/Sigma-Aldrich/etc would sell sodium nitrite to a buyer without an approved account (though VWR if I recall correctly won't sell chemicals at all to residential addresses, even sodium chloride, so it's not necessarily the best comparison).
