Hydroxylamine hydrochloride (CAS 5470-11-1) is a multifunctional but high-risk chemical:
Synthetic criticality: An irreplaceable intermediate for the synthesis of pharmaceuticals, pesticides and high-end materials;
High-risk operation: Strong corrosiveness and moderate toxicity require strict protection. Storage should be protected from moisture and heat.
Industrial universality: It is applied from the rubber industry to analysis and testing, with a purity requirement of ≥98% (industrial grade).
Industrial reducing agents and imaging agents:
Organic synthesis: Preparation of oxime compounds for the detection of aldehydes and ketones.
Pharmaceutical intermediates: Synthesis of anti-cancer drugs (hydroxyurea), sulfonamide drugs (sulfamethoxazole), and pesticides (methomyl).
Materials and Chemical Engineering
Rubber industry: As a short-term stop agent, it prevents the increase in viscosity caused by cross-linking.
Dyes and oils: Preparation of indigo intermediate, fatty acid antioxidant.
Analytical Chemistry
Electrochemical depolarizer: Used for the analysis of metal components (such as magnesium), and the detection of reducing properties of formaldehyde, camphor, etc.
Toxicity data:
Moderate toxicity: Oral LD₅₀ in mice was 408 mg/kg.
Irritation: Strongly corrosive to skin, eyes and respiratory tract. Contact can cause burns (Risk identification: R34, R36/38).
Hazardous characteristics:
When heated, it decomposes to release corrosive fumes (hydrogen chloride, nitrogen oxide), and may react violently with strong oxidants.
Protective measures:
When operating, wear anti-corrosion gloves, goggles and gas masks, and carry out the operation in a fume hood.
In case of skin contact, rinse immediately with plenty of water. If inhaled, move to a place with fresh air.
