1-Phenyltetrazole-5-thiol CAS 86-93-1

1. As a key heterocyclic intermediate, 2-Amino-4-chloro-6-methylpyrimidine is widely used in the synthesis of pharmaceuticals, especially in the preparation of antiviral, antibacterial, and anti-tumor, providing a stable pyrimidine scaffold with amino, chloro, and methyl substituents to enhance the biological activity and targeting of target compounds.
2. 2-Amino-4-chloro-6-methylpyrimidine is applied in the field of agrochemicals for the synthesis of high-efficiency pesticides, including herbicides, insecticides, and fungicides, leveraging its reactive functional groups to improve the efficacy and selectivity of agricultural chemicals.
3. 2-Amino-4-chloro-6-methylpyrimidine is used in organic synthesis as a versatile building block for constructing complex heterocyclic compounds, participating in substitution, condensation, and cyclization reactions to meet the needs of custom organic synthesis and scientific research.

1. Store in a cool, dry, well-ventilated warehouse with a temperature controlled at 15-25℃, away from direct sunlight, high temperatures, and humid environments to prevent the product from absorbing moisture, caking, or decomposing.
2. Keep the container tightly sealed to isolate air and moisture, avoid mixing with strong oxidants, strong acids, strong bases, and reducing agents, as these may trigger chemical reactions (such as hydrolysis, substitution) that reduce product purity.
3. Operate in a fume hood with adequate ventilation, wear chemical-resistant gloves, safety goggles, and a lab coat during handling; avoid direct skin and eye contact, and prevent inhalation of dust or vapor.
4. Use dry, clean equipment for weighing and transfer to avoid moisture-induced reactions, and do not mix with food, feed, or pharmaceuticals to prevent contamination.

1. Causes mild to moderate skin and eye irritation; contact with skin may lead to redness, itching, and dryness, while eye contact can cause stinging, tearing, and mild inflammation; sensitive individuals may experience allergic reactions.
2. Harmful if inhaled or swallowed; inhalation of dust or vapor may cause respiratory tract irritation, dizziness, and nausea, and ingestion can lead to gastrointestinal discomfort, vomiting, and abdominal pain.
3. In case of skin contact, immediately remove contaminated clothing and rinse the affected area with plenty of running water for at least 10-15 minutes; if irritation persists, seek medical attention.
4. In case of eye contact, rinse cautiously with water for at least 15 minutes, remove contact lenses if present, and continue rinsing before consulting a physician.

1. Possesses three reactive functional groups (amino, chloro, methyl) on the pyrimidine ring, enabling flexible chemical transformations (e.g., nucleophilic substitution of chlorine, amidation of amino group), which can adapt to diverse synthesis needs in pharmaceutical and agrochemical fields.
2. Exhibits 2-Amino-4-chloro-6-methylpyrimidine good chemical stability under mild reaction conditions, is not easy to decompose, and maintains consistent performance in multi-step synthesis, reducing reaction losses and improving product yield.
3. Has good solubility in common organic solvents (e.g., ethanol, methanol, dichloromethane, ethyl acetate), compatible with most organic reaction systems, simplifying the synthesis process and improving operation efficiency.
